curl_setopt_array
Remember:
- 'Server-side' cookies exists as information even before they were set on browser agent(HTTP COOKIE HEADER),
- javascript cookies does NOT exists as information before they were set on browser agent,
so, if you're trying to save cookies using CURLOPT_COOKIEJAR to a local file, that cookie must be server - side cookie, otherwise you are wasting time, javascript-produced cookies only exists when client browser's JS interpreter set them.

Список параметров
-
ch -
Дескриптор cURL, полученный из curl_init().
-
option -
Устанавливаемый параметр CURLOPT_XXX.
-
value -
Значение параметра
option.Для следующих значений параметра
option, параметрvalueдолжен быть типа bool:Параметр Устанавливаемое значение valueЗамечания CURLOPT_AUTOREFERERTRUEдля автоматической установки поля Referer: в запросах, перенаправленных заголовком Location:.CURLOPT_BINARYTRANSFERTRUEдля возврата необработанного ответа при использовании константыCURLOPT_RETURNTRANSFER.CURLOPT_COOKIESESSIONTRUEдля указания текущему сеансу начать новую "сессию" cookies. Это заставит libcurl проигнорировать все "сессионные" cookies, которые она должна была бы загрузить, полученные из предыдущей сессии. По умолчанию, libcurl всегда сохраняет и загружает все cookies, вне зависимости от того, являются ли они "сессионными" или нет. "Сессионные" cookies - это cookies без срока истечения, котоыре должны существовать только для текущей "сессии".CURLOPT_CERTINFOTRUEдля вывода информации о сертификате SSL в поток STDERR при безопасных соединениях.Доступна, начиная с версии PHP 5.3.2. Для корректной работы требует включенной опции CURLOPT_VERBOSE.CURLOPT_CRLFTRUEдля преобразования концов строк Unix в CRLF.CURLOPT_DNS_USE_GLOBAL_CACHETRUEдля использования глобального кэша DNS. Этот параметр не является потокобезопасным и по умолчанию включен.CURLOPT_FAILONERRORTRUEдля тихого окончания работы, если полученный HTTP-код больше или равен 400. Поведение по умолчанию возвращает страницу как обычно, игнорируя код.CURLOPT_FILETIMETRUEдля попытки получения даты модификации удаленного документа. Это значение может быть получено с помощью параметраCURLINFO_FILETIMEиз функции curl_getinfo().CURLOPT_FOLLOWLOCATIONTRUEдля следования любому заголовку "Location: ", отправленному сервером в своем ответе (учтите, что это происходит рекурсивно, PHP будет следовать за всеми посылаемыми заголовками "Location: ", за исключением случая, когда установлена константаCURLOPT_MAXREDIRS).CURLOPT_FORBID_REUSETRUEдля принудительного закрытия соединения после завершения его обработки так, чтобы его нельзя было использовать повторно.CURLOPT_FRESH_CONNECTTRUEдля принудительного использования нового соединения вместо закэшированного.CURLOPT_FTP_USE_EPRTTRUEдля использования EPRT (и LPRT) при активных FTP загрузках. ИспользуйтеFALSEдля того, чтобы отключить EPRT и LPRT и использовать только PORT.CURLOPT_FTP_USE_EPSVTRUEдля первоначальной пробы команды EPSV при FTP передачах. Если команда не удалась, будет произведен обратный откат к PASV. Установите вFALSEдля отключения EPSV.CURLOPT_FTP_CREATE_MISSING_DIRSTRUEдля создания отсутствующих директорий, если FTP-операция обнаруживает несуществующий путь.CURLOPT_FTPAPPENDTRUEдля записи удаленного файла в конец, вместо перезаписывания его поверх существующего файла.CURLOPT_FTPASCIIПсевдоним CURLOPT_TRANSFERTEXT. Используйте его вместо этого.CURLOPT_FTPLISTONLYTRUEдля возврата только списка имен из FTP директории.CURLOPT_HEADERTRUEдля включения заголовков в вывод.CURLINFO_HEADER_OUTTRUEдля отслеживания строки запроса дескриптора.Доступен, начиная с версии PHP 5.1.3. Префикс CURLINFO_употреблен специально.CURLOPT_HTTPGETTRUEдля сброса метода HTTP-запроса в метод GET. Так как GET используется по умолчанию, этот параметр необходим только в случае, если метод запроса был ранее изменен.CURLOPT_HTTPPROXYTUNNELTRUEдля туннелирования через указанный HTTP-прокси.CURLOPT_MUTETRUEдля полного отключения сообщений функций cURL.CURLOPT_NETRCTRUEдля считывания файла ~/.netrc на предмет логина и пароля для удаленного сайта, с которым устанавливается соединение.CURLOPT_NOBODYTRUEдля исключения тела ответа из вывода. Метод запроса устанавливается в HEAD. Смена этого параметра вFALSEне меняет его обратно в GET.CURLOPT_NOPROGRESSTRUEдля отмены индиктора прогресса при передачах cURL.Замечание:
PHP автоматически устанавливает этот параметр в
TRUE, меняйте его только для отладочных целей.CURLOPT_NOSIGNALTRUEдля игнорирования любой функции cURL, посылающей сигналы PHP процессу. Этот параметр включен по умолчанию в многопоточных SAPIs для корректной работы таймаут параметров.Добавлен в cURL 7.10. CURLOPT_POSTTRUEдля использования обычного HTTP POST. Данный метод POST использует обычный application/x-www-form-urlencoded, обычно используемый в HTML-формах.CURLOPT_PUTTRUEдля загрузки файла методом HTTP PUT. Используемый файл должен быть установлен с помощью параметровCURLOPT_INFILEиCURLOPT_INFILESIZE.CURLOPT_RETURNTRANSFERTRUEдля возврата результата передачи в качестве строки из curl_exec() вместо прямого вывода в браузер.CURLOPT_SSL_VERIFYPEERFALSEдля остановки cURL от проверки сертификата узла сети. Альтернативные сверяемые сертификаты могут быть указаны с помощью параметраCURLOPT_CAINFOили директории с сертификатами, указываемой параметромCURLOPT_CAPATH.По умолчанию равно TRUEначиная с версии cURL 7.10. Дистрибутив по умолчанию устанавливается начиная с версии cURL 7.10.CURLOPT_TRANSFERTEXTTRUEдля использования ASCII режима при FTP передачах. При использовании LDAP данные возвращаются простым текстом вместо HTML. В Windows системах поток STDOUT не устанавливается в бинарный режим.CURLOPT_UNRESTRICTED_AUTHTRUEдля продолжения посылки логина и пароля при редиректах (при использованииCURLOPT_FOLLOWLOCATION), даже при изменении имени хоста.CURLOPT_UPLOADTRUEдля подготовки к загрузке файла на сервер.CURLOPT_VERBOSETRUEдля вывода дополнительной информации. Записывает вывод в поток STDERR, или файл, указанный параметромCURLOPT_STDERR.Для следующих значений параметра
option, параметрvalueдолжен быть типа integer:Параметр Устанавливаемое значение valueЗамечания CURLOPT_BUFFERSIZEРазмер буфера, используемого при каждом чтении. Однако, нет никакой гарантии что данный запрос будет завершен. Добавлен в версии cURL 7.10. CURLOPT_CLOSEPOLICYЛибо CURLCLOSEPOLICY_LEAST_RECENTLY_USED, либоCURLCLOSEPOLICY_OLDEST. Есть еще три дополнительные константы CURLCLOSEPOLICY_, но cURL на данный момент их не поддерживает.CURLOPT_CONNECTTIMEOUTКоличество секунд ожидания при попытке соединения. Используйте 0 для бесконечного ожидания. CURLOPT_CONNECTTIMEOUT_MSКоличество миллисекунд ожидания при попытке соединения. Используйте 0 для бесконечного ожидания. Если библиотека libcurl скомпилирована с использованием стандартного системного преобразователя имен, то соединение будет по-прежнему использовать полносекундное ожидание в качестве тайм-аута с минимально допустимым тайм-аутом в 1 секунду. Добавлен в версии cURL 7.16.2. Доступно, начиная с версии PHP 5.2.3. CURLOPT_DNS_CACHE_TIMEOUTКоличество секунд, в течение которых в памяти хранятся DNS-записи. По умолчанию этот параметр равен 120 (2 минуты). CURLOPT_FTPSSLAUTHМетод FTP аутентификации (в активном режиме): CURLFTPAUTH_SSL (сначала проверяется SSL), CURLFTPAUTH_TLS (сначала проверяется TLS) или CURLFTPAUTH_DEFAULT (cURL решает сама). Добавлен в версии cURL 7.12.2. CURLOPT_HTTP_VERSIONCURL_HTTP_VERSION_NONE(по умолчанию, CURL сама выбирает используемую версию),CURL_HTTP_VERSION_1_0(принудительное использование HTTP/1.0), orCURL_HTTP_VERSION_1_1(принудительное использование HTTP/1.1).CURLOPT_HTTPAUTHИспользуемые HTTP методы авторизации. Используемые параметры:
CURLAUTH_BASIC,CURLAUTH_DIGEST,CURLAUTH_GSSNEGOTIATE,CURLAUTH_NTLM,CURLAUTH_ANY, andCURLAUTH_ANYSAFE.Можно использовать побитовый оператор | (или) для комбинации нескольких методов вместе. В этом случае cURL опросит сервер на предмет поддерживаемых методов авторизации и выберет лучший из них.
CURLAUTH_ANY- это псевдоним CURLAUTH_BASIC | CURLAUTH_DIGEST | CURLAUTH_GSSNEGOTIATE | CURLAUTH_NTLM.CURLAUTH_ANYSAFE- это псевдоним CURLAUTH_DIGEST | CURLAUTH_GSSNEGOTIATE | CURLAUTH_NTLM.CURLOPT_INFILESIZEОжидаемый размер файла, в байтах, при загрузке файла на удаленный сервер. Учтите, что использование этой опции не остановит дальнейшую посылку данных, превышающих это значение, так как посылаемые данные зависят от результата CURLOPT_READFUNCTION.CURLOPT_LOW_SPEED_LIMITВерхний порог скорости передачи данных, в байтах в секунду. Проверка происходит в течение CURLOPT_LOW_SPEED_TIMEсекунд, после чего PHP считает передачу слишком медленной и прерывает ее.CURLOPT_LOW_SPEED_TIMEМаксимальное количество секунд, в течение которых скорость передачи не должна превышать CURLOPT_LOW_SPEED_LIMIT, иначе PHP пометит передачу как слишком медленную и прекратит ее.CURLOPT_MAXCONNECTSМаксимальное количество постоянных соединений. При достижении лимита для определения закрываемого соединения используется параметр CURLOPT_CLOSEPOLICY.CURLOPT_MAXREDIRSМаксимальное количество принимаемых редиректов. Используйте этот параметр вместе с параметром CURLOPT_FOLLOWLOCATION.CURLOPT_PORTАльтернативный порт соединения. CURLOPT_PROTOCOLSБитовая маска из значений
CURLPROTO_*. Данная маска ограничивает используемые libcurl протоколы. Это позволяет иметь libcurl, работающую с большим количеством протоколов, и ограничивать работу определенных передач только для некоторого их набора. По умолчанию, libcurl использует все поддерживаемые протоколы. Смотрите также параметрCURLOPT_REDIR_PROTOCOLS.Корректные значения протоколов:
CURLPROTO_HTTP,CURLPROTO_HTTPS,CURLPROTO_FTP,CURLPROTO_FTPS,CURLPROTO_SCP,CURLPROTO_SFTP,CURLPROTO_TELNET,CURLPROTO_LDAP,CURLPROTO_LDAPS,CURLPROTO_DICT,CURLPROTO_FILE,CURLPROTO_TFTP,CURLPROTO_ALLДобавлен в версии cURL 7.19.4. CURLOPT_PROXYAUTHМетоды авторизации HTTP, используемые при соединении с прокси-сервером. Используйте те же самые битовые маски, которые были описаны у параметра CURLOPT_HTTPAUTH. В данный момент для авторизации прокси поддерживаются толькоCURLAUTH_BASICиCURLAUTH_NTLM.Добавлен в версии cURL 7.10.7. CURLOPT_PROXYPORTНомер порта прокси-сервера, к которому осуществляется соединение. Этот номер также может быть установлен с помощью параметра CURLOPT_PROXY.CURLOPT_PROXYTYPEЛибо CURLPROXY_HTTP(по умолчанию), либоCURLPROXY_SOCKS5.Добавлен в версии cURL 7.10. CURLOPT_REDIR_PROTOCOLSБитовая маска из значений CURLPROTO_*. Данная битовая масска ограничивает протоколы используемые libcurl при редиректе (при включенном параметреCURLOPT_FOLLOWLOCATION). Это позволяет ограничить набор используемых протоколов при редиректах для некоторых передач. По умолчанию, libcurl поддерживает все протоколы, кроме FILE и SCP. В версиях, предшествовавших 7.19.4, перенаправление использовалось для всех протоколов без исключения. Смотрите также описание параметраCURLOPT_PROTOCOLSдля списка констант со значениями протоколов.Добавлен в версии cURL 7.19.4. CURLOPT_RESUME_FROMСмещение начала передачи, в байтах. CURLOPT_SSL_VERIFYHOSTИспользуйте 1 для проверки существования общего имени в сертификате SSL. Используйте 2 для проверки существования общего имени и также его совпадения с указанным хостом. В боевом окружении значение этого параметра должно быть 2 (установлено по умолчанию). CURLOPT_SSLVERSIONИспользуемая версия SSL (2 или 3). По умолчанию, PHP попытается определить ее сам, хотя в некоторых случаях ее нужно устанавливать вручную. CURLOPT_TIMECONDITIONСпособ трактовки параметра CURLOPT_TIMEVALUE. ИспользуйтеCURL_TIMECOND_IFMODSINCEдля возвращения страницы, только если она была изменена со времени, указанного в параметреCURLOPT_TIMEVALUE. Если страница не была изменена, вернется заголовок "304 Not Modified", подразумевая, что параметрCURLOPT_HEADERустановлен вTRUE. ИспользуйтеCURL_TIMECOND_IFUNMODSINCEдля обратного эффекта. По умолчанию используетсяCURL_TIMECOND_IFMODSINCE.CURLOPT_TIMEOUTМаксимально позволенное количество секунд для выполнения cURL-функций. CURLOPT_TIMEOUT_MSМаксимально позволенное количество миллисекунд для выполнения cURL-функций. Если libcurl собрана с использованием обычного системного распознавателя имен, то этот промежуток соединения все еще будет использовать секундное округление таймаутов, с минимально разрешенным таймаутом в одну секунду. Добавлен в версии cURL 7.16.2. Доступен, начиная с версии PHP 5.2.3. CURLOPT_TIMEVALUEКоличество секунд, начиная с 1 января 1970 года. Это время будет использовано параметром CURLOPT_TIMECONDITION. По умолчанию, используется параметрCURL_TIMECOND_IFMODSINCE.CURLOPT_MAX_RECV_SPEED_LARGEЕсли скорость скачки превысит это значение (указанное в байтах в секунду) в среднем в течение всей передачи, то скачка будет приостановлена для поддержания средней скорости меньше либо равной данному параметру. По умолчанию скорость не ограничивается. Добавлен в версии cURL 7.15.5. Доступен, начиная с версии PHP 5.4.0. CURLOPT_MAX_SEND_SPEED_LARGEЕсли загрузка на сервер превысит это значение (указанное в байтах в секунду) в среднем в течение всей передачи, то загрузка будет приостановлена для поддержания средней скорости меньше либо равной данному параметру. По умолчанию скорость не ограничивается. Добавлен в версии cURL 7.15.5. Доступен, начиная с версии PHP 5.4.0. CURLOPT_SSH_AUTH_TYPESБитовая маска, состоящая из одной или более констант: CURLSSH_AUTH_PUBLICKEY,CURLSSH_AUTH_PASSWORD,CURLSSH_AUTH_HOST,CURLSSH_AUTH_KEYBOARD. УстановитеCURLSSH_AUTH_ANYдля того, чтобы libcurl выбрал одну из них самостоятельно.Добавлено в cURL 7.16.1. Для следующих значений параметра
option, параметрvalueдолжен быть типа string:Параметр Устанавливаемое значение valueЗамечания CURLOPT_CAINFOИмя файла, содержащего один или более сертификатов, с которыми будут сверяться узлы. Этот параметр имеет смысл только при использовании совместно с CURLOPT_SSL_VERIFYPEER.Требует абсолютный путь. CURLOPT_CAPATHДиректория, содержащая несколько CA сертификатов. Используйте этот параметр совместно с CURLOPT_SSL_VERIFYPEER.CURLOPT_COOKIEСодержимое заголовка "Cookie: ", используемого в HTTP-запросе. Обратите внимание, что несколько cookies разделяются точкой с запятой с последующим пробелом (например, "fruit=apple; colour=red") CURLOPT_COOKIEFILEИмя файла, содержащего cookies. Данный файл должен быть в формате Netscape или просто заголовками HTTP, записанными в файл. Если в качестве имени файла передана пустая строка, то cookies сохраняться не будут, но их обработка все еще будет включена. CURLOPT_COOKIEJARИмя файла, в котором будут сохранены все внутрение cookies текущей передачи после закрытия дескриптора, например, после вызова curl_close. CURLOPT_CUSTOMREQUESTСобственный метод запроса, используемый вместо "GET" или "HEAD" при выполнении HTTP-запроса. Это полезно при запросах "DELETE" или других, более редких HTTP-запросах. Корректными значениями будут слова наподобие "GET", "POST", "CONNECT" и так далее; т.е. не вводите здесь всю строку с HTTP-запросом. Например, указание "GET /index.html HTTP/1.0\r\n\r\n" будет неправильным.
Замечание:
Не используйте эту возможность пока не убедитесь, что сервер поддерживает данный тип запроса.
CURLOPT_EGDSOCKETНаподобие CURLOPT_RANDOM_FILE, за исключением того, что имя файла устанавливается в сокет Entropy Gathering Daemon.CURLOPT_ENCODINGСодержимое заголовка "Accept-Encoding: ". Это позволяет декодировать запрос. Поддерживаемыми кодировками являются "identity", "deflate" и "gzip". Если передана пустая строка, "", посылается заголовок, содержащий все поддерживаемые типы кодировок. Добавлен в версии cURL 7.10. CURLOPT_FTPPORTЗначение, которое будет использоваться для определения IP-адреса для команды "PORT" FTP-протокола. Команда "PORT" сообщает серверу, с каким IP-адресом он должен устанавливать соединение. Это может быть IP-адрес, имя хоста, имя сетевого интерфейса (под Unix), или просто '-' для использования системного IP-адреса по умолчанию. CURLOPT_INTERFACEИмя используемого сетевого интерфейса. Может быть именем интерфейса, IP адресом или именем хоста. CURLOPT_KEYPASSWDПароль, который требуется для использования приватного ключа CURLOPT_SSLKEYилиCURLOPT_SSH_PRIVATE_KEYFILE.Добавлено в cURL 7.16.1. CURLOPT_KRB4LEVELУровень безопасности KRB4 (Kerberos 4). Любое из следующих значений (в порядке от слабого к самому сильному) корректно: "clear", "safe", "confidential", "private".. Если указанная строка отличается от данных значений, будет использовано значение "private". Установка этого параметра в NULLполностью отключит безопасность KRB4. На данный момент безопасность KRB4 работает только с FTP транзакциями.CURLOPT_POSTFIELDSВсе данные, передаваемые в HTTP POST-запросе. Для передачи файла, укажите перед именем файла @, а также используйте полный путь к файлу. Тип файла также может быть указан с помощью формата ';type=mimetype', следующим за именем файла. Этот параметр может быть передан как в качестве url-закодированной строки, наподобие 'para1=val1¶2=val2&...', так и в виде массива, ключами которого будут имена полей, а значениями - их содержимое. Если valueявляется массивом, заголовок Content-Type будет установлен в значение multipart/form-data. Начиная с версии PHP 5.2.0, при передаче файлов с префиксом @,valueдолжен быть массивом.CURLOPT_PROXYHTTP-прокси, через который будут направляться запросы. CURLOPT_PROXYUSERPWDЛогин и пароль, записанные в виде "[username]:[password]", используемые при соединении через прокси. CURLOPT_RANDOM_FILEИмя файла, используемого для инициализации генератора случайных чисел для SSL. CURLOPT_RANGEДиапазон данных, которые нужно загрузить, в формате "X-Y", причем либо X, либо Y могут быть опущены. Протокол HTTP также поддерживает передачу нескольких диапазонов, разделенных запятыми, они задаются в формате "X-Y,N-M". CURLOPT_REFERERСодержимое заголовка "Referer: ", который будет использован в HTTP-запросе. CURLOPT_SSH_HOST_PUBLIC_KEY_MD5Строка, содержащая 32 шестнадцатеричных цифры. Строка должна являться контрольной суммой по алгоритму MD5 публичного ключа удаленного компьютера и libcurl будет сбрасывать соединение к удаленному хосту до тех пор, пока контрольная сумма не будет соответствовать публичному ключу. Эта опция предназначена только для передачи данных с помощью SCP и SFTP. Добавлено в cURL 7.17.1. CURLOPT_SSH_PUBLIC_KEYFILEИмя файла для вашего публичного ключа. Если не задано, то libcurl использует по умолчанию файл $HOME/.ssh/id_dsa.pub, если переменная окружения HOME установлена и файл "id_dsa.pub" в текущей директории, если переменная HOME не установлена. Добавлено в cURL 7.16.1. CURLOPT_SSH_PRIVATE_KEYFILEИмя файла для вашего приватного ключа. Если не задано, то libcurl использует по умолчанию файл $HOME/.ssh/id_dsa, если переменная окружения HOME установлена и файл "id_dsa" в текущей директории, если переменная HOME не установлена. Если файл защищен паролем, установите пароль с помощью CURLOPT_KEYPASSWD.Добавлено в cURL 7.16.1. CURLOPT_SSL_CIPHER_LISTСписок шифров, используемый в SSL-передачах. Например, RC4-SHA и TLSv1 являются корректными списками шифров. CURLOPT_SSLCERTИмя файла с корректно отформатированным PEM-сертификатом. CURLOPT_SSLCERTPASSWDПароль, необходимый для использования сертификата CURLOPT_SSLCERT.CURLOPT_SSLCERTTYPEФормат сертификата. Поддерживаются форматы "PEM" (по умолчанию), "DER" и "ENG". Добавлен в версии cURL 7.9.3. CURLOPT_SSLENGINEИдентификатор механизма шифрования для закрытого ключа SSL, указанного в параметре CURLOPT_SSLKEY.CURLOPT_SSLENGINE_DEFAULTИдентификатор механизма шифрования, используемого для ассиметричных операций шифрования. CURLOPT_SSLKEYИмя файла с закрытым ключом SSL. CURLOPT_SSLKEYPASSWDТайный пароль, необходимый для использования закрытого ключа SSL, указанного параметром
CURLOPT_SSLKEY.Замечание:
Так как этот параметр содержит ценный пароль, помните, что данный PHP-скрипт нужно хранить в безопасном месте.
CURLOPT_SSLKEYTYPEТип закрытого ключа SSL, указанного в параметре CURLOPT_SSLKEY. Поддерживаются следующие типы ключей: "PEM" (по умолчанию), "DER" и "ENG".CURLOPT_URLЗагружаемый URL. Данный параметр может быть также установлен при инициализации сенса с помощью curl_init(). CURLOPT_USERAGENTСодержимое заголовка "User-Agent: ", посылаемого в HTTP-запросе. CURLOPT_USERPWDЛогин и пароль, используемые при соединении, указанные в формате "[username]:[password]". Для следующих значений параметра
option, параметрvalueдолжен быть массивом:Параметр Устанавливаемое значение valueЗамечания CURLOPT_HTTP200ALIASESМассив HTTP 200 ответов, которые будут трактоваться корректными ответами, а не ошибочными. Добавлен в версии cURL 7.10.3. CURLOPT_HTTPHEADERМассив устанавливаемых HTTP-заголовков, в формате array('Content-type: text/plain', 'Content-length: 100')CURLOPT_POSTQUOTEМассив FTP-команд, выполняемых на сервере, после выполнения FTP-запроса. CURLOPT_QUOTEМассив FTP-команд, выполняемых на сервере, перед выполнением FTP-запроса. Для следующих значений параметра
option, параметрvalueдолжен быть потоковым дескриптором (возвращаемым, например, функцией fopen()):Параметр Устанавливаемое значение valueCURLOPT_FILEФайл, в который будет записан результат передачи. По умолчанию используется поток вывода STDOUT (окно браузера). CURLOPT_INFILEФайл, из которого должно идти чтение данных, при загрузке на сервер. CURLOPT_STDERRАльтернативное файл для вывода ошибок, используемый вместо потока ошибок STDERR. CURLOPT_WRITEHEADERФайл, в который будут записаны заголовки текущей операции. Для следующих значений параметра
option, параметрvalueдолжен быть корректной строкой, указывающей имя callback-функции:Параметр Устанавливаемое значение valueCURLOPT_HEADERFUNCTIONИмя callback-функции, принимающей два параметра. Первым параметром является дескриптор cURL, вторым параметром является строка с записываемыми заголовками. Заголовки должны быть записаны с помощью данной callback-функции. Должна возвратить количество записанных байт. CURLOPT_PASSWDFUNCTIONИмя callback-функции, принимающей три параметра. Первым параметром является дескриптор cURL, вторым параметром является строка с запросом пароля, третьим параметром является максимальная длина пароля. Должна возвратить строку, содержащую пароль. CURLOPT_PROGRESSFUNCTIONИмя callback-функции, принимающей три параметра. Первым параметром является дескриптор cURL, вторым параметром является дескриптор файла, а третьим параметром - его длина. Должна возвратить строку с данными. CURLOPT_READFUNCTIONИмя callback-функции, принимающей три параметра. Первым параметром является дескриптор cURL, вторым параметром является ресурс потока, переданный cURL через опцию CURLOPT_INFILE, а третьим параемтром является максимально разрешенное количество данных для чтения. Callback-функция должна возвратить строку, с длиной не превышающей запрошенного количества данных, обычно с помощью чтения из переданного потокового ресурса. Должна возвратить пустую строку для сигнала о конце файла EOF.CURLOPT_WRITEFUNCTIONИмя callback-функции, принимающей два параметра. Первым параметром является дескриптор cURL, а вторым параметром является строка с записываемыми данными. Данные должны быть сохранены с помощью данной функции. Она должна возвратить точное количество записанных байт, иначе закачка будет прервана с ошибкой.

Passing in PHP's $_SESSION into your cURL call:
<?php
session_start();
$strCookie = 'PHPSESSID=' . $_COOKIE['PHPSESSID'] . '; path=/';
session_write_close();
$curl_handle = curl_init('enter_external_url_here');
curl_setopt( $curl_handle, CURLOPT_COOKIE, $strCookie );
curl_exec($curl_handle);
curl_close($curl_handle);
?>
This worked great for me. I was calling pages from the same server and needed to keep the $_SESSION variables. This passes them over. If you want to test, just print_r($_SESSION);
Enjoy!

I've been stuck when using the CURLOPT_CONNECTTIMEOUT_MS constant. In fact, on my PHP version (5.3.1) it's not a number but rather a string. Same thing for CURLOPT_TIMEOUT_MS.
I got this error: Warning: curl_setopt() expects parameter 2 to be long, string given
If you are experiencing simular problems, you can replace the constant with the actual number or (re)define the constant.
CURLOPT_TIMEOUT_MS should be 155
CURLOPT_CONNECTTIMEOUT_MS should be 156
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT_MS, 2500); // error
curl_setopt($ch, 156, 2500); // problem solved

As of php 5.3 CURLOPT_PROGRESSFUNCTION its supported here's how:
<?php
function callback($download_size, $downloaded, $upload_size, $uploaded)
{
// do your progress stuff here
}
$ch = curl_init('http://www.example.com');
// This is required to curl give us some progress
// if this is not set to false the progress function never
// gets called
curl_setopt($ch, CURLOPT_NOPROGRESS, false);
// Set up the callback
curl_setopt($ch, CURLOPT_PROGRESSFUNCTION, 'callback');
// Big buffer less progress info/callbacks
// Small buffer more progress info/callbacks
curl_setopt($ch, CURLOPT_BUFFERSIZE, 128);
$data = curl_exec($ch);
?>
Hope this help.

I spent a couple of days trying to POST a multi-dimensional array of form fields, including a file upload, to a remote server to update a product. Here are the breakthroughs that FINALLY allowed the script to run as desired.
Firstly, the HTML form used input names like these:
<input type="text" name="product[name]" />
<input type="text" name="product[cost]" />
<input type="file" name="product[thumbnail]" />
in conjunction with two other form inputs not part of the product array
<input type="text" name="method" value="put" />
<input type="text" name="mode" />
I used several cURL options, but the only two (other than URL) that mattered were:
curl_setopt($handle, CURLOPT_POST, true);
curl_setopt($handle, CURLOPT_POSTFIELDS, $postfields);
Pretty standard so far.
Note: headers didn't need to be set, cURL automatically sets headers (like content-type: multipart/form-data; content-length...) when you pass an array into CURLOPT_POSTFIELDS.
Note: even though this is supposed to be a PUT command through an HTTP POST form, no special PUT options needed to be passed natively through cURL. Options such as
curl_setopt($handle, CURLOPT_HTTPHEADER, array('X-HTTP-Method-Override: PUT', 'Content-Length: ' . strlen($fields)));
or
curl_setopt($handle, CURLOPT_PUT, true);
or
curl_setopt($handle, CURLOPT_CUSTOMREQUEST, "PUT);
were not needed to make the code work.
The fields I wanted to pass through cURL were arranged into an array something like this:
$postfields = array("method" => $_POST["method"],
"mode" => $_POST["mode"],
"product" => array("name" => $_POST["product"],
"cost" => $_POST["product"]["cost"],
"thumbnail" => "@{$_FILES["thumbnail"]["tmp_name"]};type={$_FILES["thumbnail"]["type"]}")
);
-Notice how the @ precedes the temporary filename, this creates a link so PHP will upload/transfer an actual file instead of just the file name, which would happen if the @ isn't included.
-Notice how I forcefully set the mime-type of the file to upload. I was having issues where images filetypes were defaulting to octet-stream instead of image/png or image/jpeg or whatever the type of the selected image.
I then tried passing $postfields straight into curl_setopt($this->handle, CURLOPT_POSTFIELDS, $postfields); but it didn't work.
I tried using http_build_query($postfields); but that didn't work properly either.
In both cases either the file wouldn't be treated as an actual file and the form data wasn't being sent properly. The problem was HTTP's methods of transmitting arrays. While PHP and other languages can figure out how to handle arrays passed via forms, HTTP isn't quite as sofisticated. I had to rewrite the $postfields array like so:
$postfields = array("method" => $_POST["method"],
"mode" => $_POST["mode"],
"product[name]" => $_POST["product"],
"product[cost]" => $_POST["product"]["cost"],
"product[thumbnail]" => "@{$_FILES["thumbnail"]["tmp_name"]}");
curl_setopt($handle, CURLOPT_POSTFIELDS, $postfields);
This, without the use of http_build_query, solved all of my problems. Now the receiving host outputs both $_POST and $_FILES vars correctly.

If you are trying to update something on your server and you need to handle this update operation by PUT;
<?php
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
curl_setopt($ch, CURLOPT_PUT, 1);
?>
are "useless" without;
<?php
curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-HTTP-Method-Override: PUT'));
?>
Example;
Updating a book data in database identified by "id 1";
--cURL Part--
<?php
$data = http_build_query($_POST);
// or
$data = http_build_query(array(
'name' => 'PHP in Action',
'price' => 10.9
));
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://api.localhost/rest/books/1");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT"); // no need anymore
// or
// curl_setopt($ch, CURLOPT_PUT, 1); // no need anymore
curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-HTTP-Method-Override: PUT'));
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$ce = curl_exec($ch);
curl_close($ch);
print_r($ce);

--API class--
<?php
public function putAction() {
echo "putAction() -> id: ". $this->_getParam('id') ."\n";

Note that if you put a certificate chain in a PEM file, the certificates need to be ordered so that each certificate is followed by its issuer (i.e., root last.)

About CURLOPT_COOKIEJAR and CURLOPT_COOKIEFILE, and which / how to use.
- CURLOPT_COOKIEJAR is used when cURL is reading cookie data from disk.
- CURLOPT_COOKIEFILE is used when cURL is writing the cookie data to disk.
So you need to specify both (and set the same file location on both) when working with sessions for example.

If you want cURL to timeout in less than one second, you can use CURLOPT_TIMEOUT_MS, although there is a bug/"feature" on "Unix-like systems" that causes libcurl to timeout immediately if the value is < 1000 ms with the error "cURL Error (28): Timeout was reached". The explanation for this behavior is:
"If libcurl is built to use the standard system name resolver, that portion of the transfer will still use full-second resolution for timeouts with a minimum timeout allowed of one second."
What this means to PHP developers is "You can use this function without testing it first, because you can't tell if libcurl is using the standard system name resolver (but you can be pretty sure it is)"
The problem is that on (Li|U)nix, when libcurl uses the standard name resolver, a SIGALRM is raised during name resolution which libcurl thinks is the timeout alarm.
The solution is to disable signals using CURLOPT_NOSIGNAL. Here's an example script that requests itself causing a 10-second delay so you can test timeouts:
<?php
if (!isset($_GET['foo'])) {
// Client
$ch = curl_init('http://localhost/test/test_timeout.php?foo=bar');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_NOSIGNAL, 1);
curl_setopt($ch, CURLOPT_TIMEOUT_MS, 200);
$data = curl_exec($ch);
$curl_errno = curl_errno($ch);
$curl_error = curl_error($ch);
curl_close($ch);
if ($curl_errno > 0) {
echo "cURL Error ($curl_errno): $curl_error\n";
} else {
echo "Data received: $data\n";
}
} else {
// Server
sleep(10);
echo "Done.";
}
?>

I had problems with the Wikimedia software and sending a POST request where the data was more than 1024 bytes long. I traced this to cURL adding: Expect: 100-continue to the headers.
I added curl_setopt($ch,CURLOPT_HTTPHEADER,array("Expect:")); and that suppresses the Expect line.

If you wish to find the size of the file you are streaming and use it as your header this is how:
<?php
function write_function($curl_resource, $string)
{
if(curl_getinfo($curl_resource, CURLINFO_SIZE_DOWNLOAD) <= 2000)
{
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Description: File Transfer');
header("Content-Transfer-Encoding: binary");
header("Content-Type: ".curl_getinfo($curl_resource, CURLINFO_CONTENT_TYPE)."");
header("Content-Length: ".curl_getinfo($curl_resource, CURLINFO_CONTENT_LENGTH_DOWNLOAD)."");
}
print $string;
return mb_strlen($string, '8bit');
}
?>
1440 is the the default number of bytes curl will call the write function (BUFFERSIZE does not affect this, i actually think you can not change this value), so it means the headers are going to be set only one time.
write_function must return the exact number of bytes of the string, so you can return a value with mb_strlen.

If you are trying to use CURLOPT_FOLLOWLOCATION and you get this warning:
Warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION cannot be activated when in safe_mode or an open_basedir is set...
then you will want to read http://www.php.net/ChangeLog-4.php which says "Disabled CURLOPT_FOLLOWLOCATION in curl when open_basedir or safe_mode are enabled." as of PHP 4.4.4/5.1.5. This is due to the fact that curl is not part of PHP and doesn't know the values of open_basedir or safe_mode, so you could comprimise your webserver operating in safe_mode by redirecting (using header('Location: ...')) to "file://" urls, which curl would have gladly retrieved.
Until the curl extension is changed in PHP or curl (if it ever will) to deal with "Location:" headers, here is a far from perfect remake of the curl_exec function that I am using.
Since there's no curl_getopt function equivalent, you'll have to tweak the function to make it work for your specific use. As it is here, it returns the body of the response and not the header. It also doesn't deal with redirection urls with username and passwords in them.
<?php
function curl_redir_exec($ch)
{
static $curl_loops = 0;
static $curl_max_loops = 20;
if ($curl_loops++ >= $curl_max_loops)
{
$curl_loops = 0;
return FALSE;
}
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch);
list($header, $data) = explode("\n\n", $data, 2);
$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
if ($http_code == 301 || $http_code == 302)
{
$matches = array();
preg_match('/Location:(.*?)\n/', $header, $matches);
$url = @parse_url(trim(array_pop($matches)));
if (!$url)
{
//couldn't process the url to redirect to
$curl_loops = 0;
return $data;
}
$last_url = parse_url(curl_getinfo($ch, CURLINFO_EFFECTIVE_URL));
if (!$url['scheme'])
$url['scheme'] = $last_url['scheme'];
if (!$url['host'])
$url['host'] = $last_url['host'];
if (!$url['path'])
$url['path'] = $last_url['path'];
$new_url = $url['scheme'] . '://' . $url['host'] . $url['path'] . ($url['query']?'?'.$url['query']:'');
curl_setopt($ch, CURLOPT_URL, $new_url);
debug('Redirecting to', $new_url);
return curl_redir_exec($ch);

About the CURLOPT_HTTPHEADER option, it took me some time to figure out how to format the so-called 'Array'. It fact, it is a list of strings. If Curl was already defining a header item, yours will replace it. Here is an example to change the Content Type in a POST:
<?php curl_setopt ($ch, CURLOPT_HTTPHEADER, Array("Content-Type: text/xml")); ?>

If you want to connect to a secure server for posting info/reading info, you need to make cURL with the openSSL options. Then the sequence is nearly identical to the previous example (except http_S_://, and possibly add the useragent):
<?php
curl_setopt($ch, CURLOPT_URL,"https://example.com");
//some sites only accept your request if your browser looks legit, so send a useragent profile...
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");

Please everyone, stop setting CURLOPT_SSL_VERIFYPEER to false or 0. If your PHP installation doesn't have an up-to-date CA root certificate bundle, download the one at the curl website and save it on your server:
http://curl.haxx.se/docs/caextract.html
Then set a path to it in your php.ini file, e.g. on Windows:
curl.cainfo=c:\php\cacert.pem
Turning off CURLOPT_SSL_VERIFYPEER allows man in the middle (MITM) attacks, which you don't want!

Handling redirections with curl if safe_mode or open_basedir is enabled. The function working transparent, no problem with header and returntransfer options. You can handle the max redirection with the optional second argument (the function is set the variable to zero if max redirection exceeded).
Second parameter values:
- maxredirect is null or not set: redirect maximum five time, after raise PHP warning
- maxredirect is greather then zero: no raiser error, but parameter variable set to zero
- maxredirect is less or equal zero: no follow redirections
<?php
function curl_exec_follow(/*resource*/ $ch, /*int*/ &$maxredirect = null) {
$mr = $maxredirect === null ? 5 : intval($maxredirect);
if (ini_get('open_basedir') == '' && ini_get('safe_mode' == 'Off')) {
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, $mr > 0);
curl_setopt($ch, CURLOPT_MAXREDIRS, $mr);
} else {
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
if ($mr > 0) {
$newurl = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);
$rch = curl_copy_handle($ch);
curl_setopt($rch, CURLOPT_HEADER, true);
curl_setopt($rch, CURLOPT_NOBODY, true);
curl_setopt($rch, CURLOPT_FORBID_REUSE, false);
curl_setopt($rch, CURLOPT_RETURNTRANSFER, true);
do {
curl_setopt($rch, CURLOPT_URL, $newurl);
$header = curl_exec($rch);
if (curl_errno($rch)) {
$code = 0;
} else {
$code = curl_getinfo($rch, CURLINFO_HTTP_CODE);
if ($code == 301 || $code == 302) {
preg_match('/Location:(.*?)\n/', $header, $matches);
$newurl = trim(array_pop($matches));
} else {
$code = 0;
}
}
} while ($code && --$mr);
curl_close($rch);

trigger_error('Too many redirects. When following redirects, libcurl hit the maximum amount.', E_USER_WARNING);

if you want to do a GET request with additional body data it will become tricky not to implicitly change the request to a POST, like many notes below correctly state.
So to do the analogy of command line's
curl -XGET 'http://example.org?foo=bar' -d '<baz>some additional data</baz>'
in PHP you'll do, besides your other necessary stuff,
<?php
curl_setopt($curlHandle, CURLOPT_CUSTOMREQUEST, 'GET');
curl_setopt($curlHandle, CURLOPT_POSTFIELDS, '<baz>some additional data</baz>');
?>
during my experiments, every other "similar" way, like e.g. CURLOPT_HTTPGET, didn't send the additional data or fell into POST.

if you need to send a SOAP string that is the CURL you must use :
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, XML_POST_URL);
curl_setopt ($ch, CURLOPT_HTTPHEADER, array('SOAPAction: ""'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_POSTFIELDS, XML_PAYLOAD);
curl_setopt($ch, CURLOPT_HEADER, 0);
$output = curl_exec($ch);
?>
Note : Having based my snipet on Chemo demonstration (oscommerce user know who he is), XML_POST_URL and XML_PAYLOAD where defined as constant with define().
The point is : at the opposite of .xml , SOAP must send the header 'SOAPAction: ""' that can be a valid URI, an empty string (that is here) or nothing ('SOAPAction: '). The later case baing not accepted by all server, the second one indicating the target is the URI used to post the SOAP.

Note that CURLOPT_RETURNTRANSFER when used with CURLOPT_WRITEFUNCTION has effectively three settings: default, true, and false.
default - callbacks will be called as expected.
true - content will be returned but callback function will not be called.
false - content will be output and callback function will not be called.
Note that CURLOPT_HEADERFUNCTION callbacks are always called.

When using CURLOPT_POSTFIELDS with an array as parameter, you have to pay high attention to user input. Unvalidated user input will lead to serious security issues.
<?php
/**
* test.php:
*/
$ch = curl_init('http://example.com');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, array(
'foo' => $_GET['bar']
));
curl_exec($ch);
?>
Requesting "test.php?bar=@/home/user/test.png" will send "test.png" to example.com.
Make sure you remove the leading "@" from user input.

Sime sites may protect themselves from remote logins by checking which site you came from.
Then you might want to use CURLOPT_REFERER.
<?php
// $url = page to POST data
// $ref_url = tell the server which page you came from (spoofing)
// $login = true will make a clean cookie-file.
// $proxy = proxy data
// $proxystatus = do you use a proxy ? true/false
function
curl_grab_page($url,$ref_url,$data,$login,$proxy,$proxystatus){
if($login == 'true') {
$fp = fopen("cookie.txt", "w");
fclose($fp);
}
$ch = curl_init();
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookie.txt");
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie.txt");
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");
curl_setopt($ch, CURLOPT_TIMEOUT, 40);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
if ($proxystatus == 'true') {
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, TRUE);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
}
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_REFERER, $ref_url);
curl_setopt($ch, CURLOPT_HEADER, TRUE);
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
ob_start();
return curl_exec ($ch); // execute the curl command
ob_end_clean();
curl_close ($ch);

When you are using CURLOPT_FILE to download directly into a file you must close the file handler after the curl_close() otherwise the file will be incomplete and you will not be able to use it until the end of the execution of the php process.
<?php
$fh = fopen('/tmp/foo', 'w');
$ch = curl_init('http://example.com/foo');
curl_setopt($ch, CURLOPT_FILE, $fh);
curl_exec($ch);
curl_close($ch);
# at this point your file is not complete and corrupted
fclose($fh);
# now you can use your file;
read_file('/tmp/foo');

FYI,
Anyone trying to connect to .NET with CURL to send a simple XML post, pay attention to the following. This will save you hours! There is a previous note that I saw either on this page, or somewhere else on this site that explains the correct way to specify the header option is to create an array, then reference the array from the CURLOPT.
ie. Do something like this:
<?php
// Req. HTTP Header Values
$header[] = "Content-type: text/xml";
// Target URL
$sendTo = "http://www.example.com";
// Post Data
$post = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n<root>\n....etc, etc,";
// Create CURL Connection
$ch = curl_init();
curl_setopt($ch, CURLOPT_USERAGENT, 'XtraDoh xAgent');
curl_setopt($ch, CURLOPT_URL, $sendTo);
curl_setopt($ch, CURLOPT_TIMEOUT, 900);
curl_setopt($ch, CURLOPT_CONNECTIONTIMEOUT, 30);
curl_setopt($ch, CURLOPT_FAILONERROR, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
?>
Notice the HTTPHEADER, $header above. I have not been able to get .NET to properly read the HTTP header as specified (in this case as text/xml) when using the following:
<?php
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type'=>'text/xml'));
?>
Although this may work when working with other PHP, IIS, or even PHP, Apache, it does not (at least in my experience) work with .NET, IIS.

if you are trying to connect to 'https://...' and after that want to work with POST data - that's the way:
<?php
$curl = curl_init();
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($curl, CURLOPT_COOKIEFILE, "cookiefile");
curl_setopt($curl, CURLOPT_COOKIEJAR, "cookiefile"); # SAME cookiefile
curl_setopt($curl, CURLOPT_URL, "url1"); # this is where you first time connect - GET method authorization in my case, if you have POST - need to edit code a bit
$xxx = curl_exec($curl);
curl_setopt($curl, CURLOPT_URL, "url2"); # this is where you are requesting POST-method form results (working with secure connection using cookies after auth)
curl_setopt($curl, CURLOPT_POSTFIELDS, "var1=value&var2=value&var3=value&"); # form params that'll be used to get form results
$xxx = curl_exec($curl);
curl_close ($curl);
echo $xxx;

If you have a mixture of strings starting with @ (at character) and files in CURLOPT_POSTFIELDS you have a problem (such as posting a tweet with attached media) because curl tries to interpret anything starting with @ as a file.
<?php
$postfields = array(
'upload_file' => '@file_to_upload.png',
'upload_text' => '@text_to_upload'
);
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, 'http://example.com/upload-test');
curl_setopt($curl, CURLOPT_POSTFIELDS, $postfields);
curl_exec($curl);
curl_close($curl);
?>
To get around this, prepend the text string with the NULL character like so:
<?php
$postfields = array(
'upload_file' => '@file_to_upload.png',
'upload_text' => sprintf("\0%s", '@text_to_upload')
);
?>

I spent a couple of days trying to upload a file using a curl post.
The problem I ran into was the filename had an '@' in the middle of it. It turned out that at least on my system if I encoded the file path using the quoted_printable_encode() function the upload works.
I'm posting this in the hopes that it will help someone else, and for my own future reference.
Code:
<?php
$filepath = '/tmp/test@example.txt';
$postdata['file'] = '@' . quoted_printable_encode($filepath);
//... supporting code.
$result = curl_exec($ch);
?>
I'm not exactly sure why this works when escaping the '@' doesn't work but it does for me.
If anyone can offer insight into why this works or a better way to handle the '@' symbol in a filename when using curl to upload I would love to hear it.
Thanks

Another note addressing the issues with servers that have open_basedir and safe mode turned on. Such an issue spawns the following E_WARNING:
Warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION cannot be activated when safe_mode is enabled or an open_basedir is set
After looking through the notes, most of the proposed manual implementations were kind of clunky and in some cases just didn't work at all. Most importantly (in my case), was the behaviour of the 302 Header. Anyway, here's the code I ended up using which has worked well for me in all cases so far, it even addresses the issue that caused FOLLOWLOCATION to be turned off in some cases :)
EDIT: Unfortunately the code itself is deemed "too long" for PHP's note system. I've uploaded it to a few paste sites below so hopefully the links will live for a while at least.

Use it as a replacement for curl_exec. For example:
<?php
$ch = curl_init("http://php.net");
var_dump(curl_exec_follow($ch, 9001));
curl_close($ch);

Be careful when changing CURLOPT_SSL_VERIFYHOST or other options to true (boolean). It may cause insecure behavior [1]
This is because boolean true casts into integer 1, and CURLOPT_SSL_VERIFYHOST = 1 is not secure behavior.

We can achieve HTML scrapper operation in 2 step operation:
Call to Remote Web Page and extract the HTML content.
Match the HTML tags using Regular Expression.
Call to Remote Web Page using PHP:
In PHP there are various ways we can call the remote webpage. But here we will be using CURL to achieve our operation.

When trying to pass a multi-dimensional array to CURLOPT_POSTFIELDS, first run it through http_build_query(). That will get rid of the Array to String conversion notice.

If you are using curl to do a soap request and consistently get the following error back:
The server cannot service the request because the media type is unsupported.
You are sending the Content-type of soap 1.2 to a 1.1 server.
Soap 1.1 needs Content-Type: text/xml;
Soap 1.2 should have Content-Type: application/soap+xml;

This may be not obvious, but if you specify the CURLOPT_POSTFIELDS and don't specify the CURLOPT_POST - it will still send POST, not GET (as you might think - since GET is default).
So the line:
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
is synonym to:
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
Even if you set the options like this (in this order):
curl_setopt($ch, CURLOPT_POST, 0);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
it will send POST, since CURLOPT_POSTFIELDS is latter.
So if you want GET - make sure you don't have CURLOPT_POSTFIELDS specified somewhere.

The description of the use of the CURLOPT_POSTFIELDS option should be emphasize, that using POST with HTTP/1.1 with cURL implies the use of a "Expect: 100-continue" header. Some web servers will not understand the handling of chunked transfer of post data.
To disable this behavior one must disable the use of the "Expect:" header with
curl_setopt($ch, CURLOPT_HTTPHEADER,array("Expect:"));

As of at least PHP 5.3.9, if you are continuing to use a cURL session handle after downloading a file and closing the file handle, you will need to change CURLOPT_FILE back to stdout, and cannot count simply on a side effect of CURLOPT_RETURNTRANSFER to do so, even if you are setting it. For example:
<?php
$ch = curl_init();
$fh = fopen('/path/to/stored/file/example_file.dat', 'w');
curl_setopt($ch, CURLOPT_FILE, $fh);
curl_setopt($ch, CURLOPT_URL, 'http://example.com/example_file.dat');
curl_exec($ch);
fflush($fh);
fclose($fh);
//must reset cURL file handle. Not doing so will cause a warning to be
//thrown and for cURL to default to output regardless
//for our example, we'll set return transfer.
curl_setopt($ch, CURLOPT_FILE, fopen('php://stdout', 'w'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_URL, 'http://example.org/index.html');
$html = curl_exec($ch); //this will now work

I noted something when using CURLOPT_POSTFIELDS in combination with arrays from PHP.
You may supply an array, but there may not be any sub-arrays in this array, as this will give Array-to-string-conversion notice.
Example:
<?php
$ch = curl_init();
# this works
$data = array('name' => 'value');
# this gives "Notice: Array to string conversion..."
$data = array('name' => array('subname' => 'subvalue'));
curl_setopt($ch, CURLOPT_URL, 'http://localhost/test.php');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_exec($ch);
?>

Make sure to set keys for array if passing to CURLOPT_POSTFIELDS.
<?php
//This can cause errors
$data = array('bar');
//Use this instead
$data = array('foo' => 'bar');
curl_setopt(CURLOPT_POSTFIELDS, $data);

CURLOPT_POST must be left unset if you want the Content-Type header set to "multipart/form-data" (e.g., when CURLOPT_POSTFIELDS is an array). If you set CURLOPT_POSTFIELDS to an array and have CURLOPT_POST set to TRUE, Content-Length will be -1 and most sane servers will reject the request. If you set CURLOPT_POSTFIELDS to an array and have CURLOPT_POST set to FALSE, cURL will send a GET request.

Sending a post file upload across a squid proxy, the request was rejected by the proxy. In the error page returned it provided among other possible causes:"Expect:" feature is being asked from a HTTP/one.zero.
Solution: Add the option <?php curl_setopt($cl,CURLOPT_HTTPHEADER,array("Expect:")); ?>. This will remove the expect http header.

When you set ($ch, curlopt_post, 1) , after you have posted your data with curl_exec , you need to set ($ch, curlopt_post, 0), Otherwise all your subsequent requests seems as a post with no postdata and some reverse proxy servers send 500 or 403 error for these case ( access denied or forbidden )!

When CURLOPT_FOLLOWLOCATION and CURLOPT_HEADER are both true and redirect/s have happened then the header returned by curl_exec() will contain all the headers in the redirect chain in the order they were encountered.
anon@mouse dot com ¶

If your POST data seems to be disappearing (POST data empty, request is being handled by the server as a GET), try rearranging the order of CURLOPT_POSTFIELDS setting with CURLOPT_NOBODY. CURLOPT_POSTFIELDS has to come AFTER CURLOPT_NOBODY setting because if it comes after it wipes out the Content-Type header that tells your URL target that the request is a POST not a GET.
Not sure if this is expected behavior but it certainly isn't documented (except on Stackoverflow.com, which is supremely unhelpful - BTW, guys over on stack overflow... once you've figured out a PHP problem, posting the solution here would save everyone extra search time).

FYI... unless you specifically set the user agent, no user agent will be sent in your request as there is no default value like some of the other options.
As others have said, not sending a user agent may cause you to not get the results that you expected, e.g., 0 byte length content, different content, etc.

A note on the way Curl posts files...
<?php
curl_setopt($ch, CURLOPT_POSTFIELDS, array('file' => '@/path/to/file.ext');
?>
will post the FULL PATH of the file in the filename field:
Content-Disposition: form-data; name="file"; filename="/path/to/file.ext"
Whereas typical browser behavior only sends the filename:
Content-Disposition: form-data; name="file"; filename="file.ext"
Workaround:
<?php
curl_setopt($ch, CURLOPT_POSTFIELDS, array('file' => '@file.ext');
$cwd = getcwd();
chdir('/path/to/');
$receivedData = curl_exec($ch);
chdir($cwd);

When POSTing with cURL, my POSTs were magically being converted to GETs and I debugged it until finding the issue. I was setting the CURLOPT_MUTE option. Not sure why this conflicts, since the documentation doesn't specify as such. Anyways, if your $_POST is empty, make sure you aren't setting CURLOPT_MUTE.
Cheers!

Be careful when setting the CURLOPT_POSTFIELDS setting using an array. The array used to set the POST fields must only contain scalar values. Multidimentional arrays or objects lacking a __toString implementation will cause Curl to error.
If there is a need to send non-scalar values using a POST request, consider serializing them before transmission.
<?php
$ch = curl_init('http://host.example.com');
// Data to post
$multiDimensional = array(
'name' = 'foo',
'data' = array(1,2,3,4),
'value' = 'bar'
);
// Will error
curl_setopt($ch, CURLOPT_POSTFIELDS, $multiDimensional);
// Data to post
$postData = array(
'name' = 'foo',
'data' = serialize(array(1,2,3,4)),
'value' = 'bar'
);
// Will not error
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);

It appears that setting CURLOPT_FILE before setting CURLOPT_RETURNTRANSFER doesn't work, presumably because CURLOPT_FILE depends on CURLOPT_RETURNTRANSFER being set.
So do this:
<?php
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FILE, $fp);
?>
not this:
<?php
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

Some additional notes for curlopt_writefunction. I struggled with this at first because it really isn't documented very well.
When you write a callback function and use it with curlopt_writefunction it will be called MULTIPLE times. Your function MUST return the ammount of data written to it each time. It is very picky about this. Here is a snippet from my code that may help you
<?php
curl_setopt($this->curl_handle, CURLOPT_WRITEFUNCTION, array($this, "receiveResponse"));
// later on in the class I wrote my receive Response method
private function receiveResponse($curlHandle,$xmldata)
{
$this->responseString = $xmldata;
$this->responseXML .= $this->responseString;
$this->length = strlen($xmldata);
$this->size += $this->length;
return $this->length;
}
?>
Now I did this for a class. If you aren't doing OOP then you will obviously need to modify this for your own use.
CURL calls your script MULTIPLE times because the data will not always be sent all at once. Were talking internet here so its broken up into packets. You need to take your data and concatenate it all together until it is all written. I was about to pull my damn hair out because I would get broken chunks of XML back from the server and at random lengths. I finally figured out what was going on. Hope this helps

For those of you wondering how to specify the content-type for a file uploaded via curl, the syntax is as follows:
<?php
$data = array('file' => '@/home/user/test.png;type=image/png');
?>
Simply adding a semicolon with the type= at the end.
Note that this has been reported not to work in all versions of PHP and I have done the following tests:
5.2.6 (libcurl 7.18.2) : Does not work
5.2.13 (libcurl 7.20.0) : Works just fine
So it might be worth updating your installation of PHP and/or libcurl if you want to be able to use this syntax

I couldn't find a way to force a curl request to go to a particular IP address, but you can do it with fsockopen:
<?php
$ip = '123.45.67.89';
$fp = fsockopen($ip, 80, $errno, $errstr, 5);
$result = '';
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
$out = "GET /path/to/the/file.ext HTTP/1.1\r\n";
$out .= "Host: www.exampl.com\r\n";
$out .= "Connection: Close\r\n\r\n";
fwrite($fp, $out);
while (!feof($fp)) {
$result .= fgets($fp, 128);
}
fclose($fp);
}
?>
I needed it to test the response from a set of servers behind a load balancer.

If you have turned on conditional gets on a curl handle, and then for a subsequent request, you don't have a good setting for CURLOPT_TIMEVALUE , you can disable If-Modified-Since checking with:
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $foo);
curl_setopt($ch, CURLOPT_TIMEVALUE, filemtime($foo_path));
curl_setopt($ch, CURLOPT_TIMECONDITION, CURLOPT_TIMECOND_IFMODIFIEDSINCE);
curl_exec($ch);
// Reuse same curl handle
curl_setopt($ch, CURLOPT_URL, $bar);
curl_setopt($ch, CURLOPT_TIMEVALUE, null); // don't know mtime
curl_setopt($ch, CURLOPT_TIMECONDITION, 0); // set it to 0, turns it off
curl_exec($ch);

You can use also use object methods as callback functions. This is usefull if your curl ressource is part of an object handling transfers.
Instead of curl_setopt($curl, CURLOPT_WRITEFUNCTION, "curl_handler_recv") you can use array($object, "method") as value for callback options.
For example:
<?php
class downloader {
private $curl;
function __construct() {
$this->curl = curl_init();
curl_setopt($this->curl, CURLOPT_WRITEFUNCTION, array($this, "curl_handler_recv"));
}
function curl_handler_recv($res, $data) {
//...
}
//...

PUT requests are very simple, just make sure to specify a content-length header and set post fields as a string.
Example:
<?php
function doPut($url, $fields)
{
$fields = (is_array($fields)) ? http_build_query($fields) : $fields;
if($ch = curl_init($url))
{
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Length: ' . strlen($fields)));
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
curl_exec($ch);
$status = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
return (int) $status;
}
else
{
return false;
}
}
if(doPut('http://example.com/api/a/b/c', array('foo' => 'bar')) == 200)
// do something
else
// do something else.
?>
You can grab the request data on the other side with:
<?php
if($_SERVER['REQUEST_METHOD'] == 'PUT')
{
parse_str(file_get_contents('php://input'), $requestData);
// Array ( [foo] => bar )
print_r($requestData);
// Do something with data...
}
?>
DELETE can be done in exactly the same way.

Hello.
During problems with "CURLOPT_FOLLOWLOCATION cannot be activated when in safe_mode or an open_basedir is set"
I was looking for solution.
I've found few methods on this page, but none of them was good enough, so I made one.
<?php
function curl_redirect_exec($ch, &$redirects, $curlopt_header = false) {
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch);
$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
if ($http_code == 301 || $http_code == 302) {
list($header) = explode("\r\n\r\n", $data, 2);
$matches = array();
preg_match('/(Location:|URI:)(.*?)\n/', $header, $matches);
$url = trim(array_pop($matches));
$url_parsed = parse_url($url);
if (isset($url_parsed)) {
curl_setopt($ch, CURLOPT_URL, $url);
$redirects++;
return curl_redirect_exec($ch, $redirects);
}
}
if ($curlopt_header)
return $data;
else {
list(,$body) = explode("\r\n\r\n", $data, 2);
return $body;
}
}
?>
Main issue in existing functions was lack of information, how many redirects was done.
This one will count it.
First parameter as usual.
Second should be already initialized integer, it will be incremented by number of done redirects.
You can set CURLOPT_HEADER if You need it.

I've found that setting CURLOPT_HTTPHEADER more than once will clear out any headers you've set previously with CURLOPT_HTTPHEADER.
Consider the following:
<?php
# ...
curl_setopt($cURL,CURLOPT_HTTPHEADER,array (
"Content-Type: text/xml; charset=utf-8",
"Expect: 100-continue"
));
# ... do some other stuff ...
curl_setopt($cURL,CURLOPT_HTTPHEADER,array (
"Accept: application/json"
));
# ...
?>
Both the Content-Type and Expect I set will not be in the outgoing headers, but Accept will.

I noticed that if you want to get current cookie file after curl_exec() - you need to close current curl handle (like it said in manual), but if you want cookies to be dumped to file after any curl_exec (without curl_close) you can:
<?php
#call it normally
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookiefile");
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookiefile");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/');
$result1 = curl_exec($ch);
#and then make a temp copy
$ch_temp=curl_copy_handle(ch);
curl_close($ch);
$ch=$ch_temp;
?>
Only this way, if you close $ch_temp - cookies wont be dumped.

If you set CURLOPT_RESUME_FROM to resume the file, and then reuse the same Curl handle to download another file, you must reset the resume status by calling curl_setopt( $ch, CURLOPT_RESUME_FROM, 0 ). It will not reset, and will apply to all subsequent transfers even if the URL is the same.

To find what encoding a given HTTP POST request uses is easy -- passing an array to CURLOPT_POSTFIELDS results in multipart/form-data:
<?php
curl_setopt(CURLOPT_POSTFIELDS, array('field1' => 'value'));
?>
Passing a URL-encoded string will result in application/x-www-form-urlencoded:
<?php
curl_setopt(CURLOPT_POSTFIELDS, array('field1=value&field2=value2'));
?>
I ran across this when integrating with both a warehouse system and an email system; neither would accept multipart/form-data, but both happily accepted application/x-www-form-urlencoded.

If you want to connect to a server which requires that you identify yourself with a certificate, use following code. Your certificate and servers certificate are signed by an authority whose certificate is in ca.ctr.
<?php
curl_setopt($ch, CURLOPT_VERBOSE, '1');
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, '1');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, '1');
curl_setopt($ch, CURLOPT_CAINFO, getcwd().'/cert/ca.crt');
curl_setopt($ch, CURLOPT_SSLCERT, getcwd().'/cert/mycert.pem');
curl_setopt($ch, CURLOPT_SSLCERTPASSWD, 'password');
?>
If your original certificate is in .pfx format, you have to convert it to .pem using following commands
# openssl pkcs12 -in mycert.pfx -out mycert.key
# openssl rsa -in mycert.key -out mycert.pem
# openssl x509 -in mycert.key >> mycert.pem

Although CURLOPT_CLOSEPOLICY and the applicable choices are valid constants, setting this option with curl_setopt() always returns false. A quick google search suggests the option is deprecated and/or never worked.

$Output = curl_exec($ch);
curl_close($ch);

If you are doing a POST, and the content length is 1,025 or greater, then curl exploits a feature of http 1.1: 100 (Continue) Status.
See http://www.w3.org/Protocols/rfc2616/rfc2616-sec8.html#sec8.2.3
* it adds a header, "Expect: 100-continue".
* it then sends the request head, waits for a 100 response code, then sends the content
Not all web servers support this though. Various errors are returned depending on the server. If this happens to you, suppress the "Expect" header with this command:
<?php
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Expect:'));
?>
See http://www.gnegg.ch/2007/02/the-return-of-except-100-continue/

Clarification for the CURLOPT_NOBODY option: by excluding the body from your request, you're effectively making a HEAD request. Use the CURLOPT_NOBODY option to return only the headers in the remote response.
Example:
<?php
function check_url($url) {
$c = curl_init();
curl_setopt($c, CURLOPT_URL, $url);
curl_setopt($c, CURLOPT_HEADER, 1); // get the header
curl_setopt($c, CURLOPT_NOBODY, 1); // and *only* get the header
curl_setopt($c, CURLOPT_RETURNTRANSFER, 1); // get the response as a string from curl_exec(), rather than echoing it
curl_setopt($c, CURLOPT_FRESH_CONNECT, 1); // don't use a cached version of the url
if (!curl_exec($c)) { return false; }
$httpcode = curl_getinfo($c, CURLINFO_HTTP_CODE);
return ($httpcode < 400);
}
?>

This is very clear in hindsight, but it still cost me several hours:
<?php curl_setopt($session, CURLOPT_HTTPPROXYTUNNEL, 1); ?>
means that you will tunnel THROUGH the proxy, as in "your communications will go as if the proxy is NOT THERE".
Why do you care? - Well, if you are trying to use, say, Paros, to debug HTTP between your cURL and the server, with CURLOPT_HTTPPROXYTUNNEL set to TRUE Paros will not see or log your traffic thus defeating the purpose and driving you nuts.
There are other cases, of course, where this option is extremely useful...

I was working on using php to interface with an authorize.net gateway, and I ran into a problem with certificates using curl to talk the https:// url.
curl_error() told me "SSL certificate problem, verify that the CA cert is OK."
I googled it and found the same "solution" over and over again: bypass verification by adding this line after curl_init():
<?php
curl_setopt($connection, CURLOPT_SSL_VERIFYPEER, false);
?>
This worked great, but I was required to verify, so here's what I did. Add the following lines:
<?php
curl_setopt($connection, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($connection, CURLOPT_CAINFO, "path:/ca-bundle.crt");
?>
with "path:/ca-bundle.crt" being the path to that certificate file. You can get this file by downloading the curl package (http://curl.haxx.se/download.html) and looking for it in the lib folder.
Feel free to email me.

Note that if you want to use a proxy and use it as a _cache_, you'll have to do:
<?php curl_setopt($ch, CURLOPT_HTTPHEADER, array("Pragma: ")); ?>
else by default Curl puts a "Pragma: no-cache" header in and thus force cache misses for all requests.

Clarification on the callback methods:
- CURLOPT_HEADERFUNCTION is for handling header lines received *in the response*,
- CURLOPT_WRITEFUNCTION is for handling data received *from the response*,
- CURLOPT_READFUNCTION is for handling data passed along *in the request*.
The callback "string" can be any callable function, that includes the array(&$obj, 'someMethodName') format.

Sometimes you can't use CURLOPT_COOKIEJAR and CURLOPT_COOKIEFILE becoz of the server php-settings(They say u may grab any files from server using these options). Here is the solution
1)Don't use CURLOPT_FOLLOWLOCATION
2)Use curl_setopt($ch, CURLOPT_HEADER, 1)
3)Grab from the header cookies like this:
preg_match_all('|Set-Cookie: (.*);|U', $content, $results);
$cookies = implode(';', $results[1]);
4)Set them using curl_setopt($ch, CURLOPT_COOKIE, $cookies);
Good Luck, Yevgen

The examples below for HTTP file upload work great, but I wanted to be able to post multiple files through HTTP upload using HTML arrays as specified in example 38.3 at

In this case, you need to set the arrays AND keys in the $post_data, it will not work with just the array names. The following example shows how this works:
<?php

$post_data['pictures[0]'] = "@cat.jpg";
$post_data['pictures[1]'] = "@dog.jpg";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://example.com/my_url.php" );

If you're getting trouble with cookie handling in curl:
- curl manages tranparently cookies in a single curl session
- the option
<?php curl_setopt($ch, CURLOPT_COOKIEJAR, "/tmp/cookieFileName"); ?>
makes curl to store the cookies in a file at the and of the curl session
- the option
<?php curl_setopt($ch, CURLOPT_COOKIEFILE, "/tmp/cookieFileName"); ?>
makes curl to use the given file as source for the cookies to send to the server.
so to handle correctly cookies between different curl session, the you have to do something like this:
<?php
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_COOKIEJAR, COOKIE_FILE_PATH);
curl_setopt ($ch, CURLOPT_COOKIEFILE, COOKIE_FILE_PATH);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec ($ch);
curl_close($ch);
return $result;
?>
in particular this is NECESSARY if you are using PEAR_SOAP libraries to build a webservice client over https and the remote server need to establish a session cookie. in fact each soap message is sent using a different curl session!!
I hope this can help someone

To further expand upon use of CURLOPT_CAPATH and CURLOPT_CAINFO...
In my case I wanted to prevent curl from talking to any HTTPS server except my own using a self signed certificate. To do this, you'll need openssl installed and access to the HTTPS Server Certificate (server.crt by default on apache)
You can then use a command simiar to this to translate your apache certificate into one that curl likes.
$ openssl x509 -in server.crt -out outcert.pem -text
Then set CURLOPT_CAINFO equal to the the full path to outcert.pem and turn on CURLOPT_SSL_VERIFYPEER.
If you want to use the CURLOPT_CAPATH option, you should create a directory for all the valid certificates you have created, then use the c_rehash script that is included with openssl to "prepare" the directory.
If you dont use the c_rehash utility, curl will ignore any file in the directory you set.

Problems can occur if you mix CURLOPT_URL with a 'Host:' header in CURLOPT_HEADERS on redirects because cURL will combine the host you explicitly stated in the 'Host:' header with the host from the Location: header of the redirect response.
In short, don't do this:
<?php
$host = "www.example.com";
$url = "http://$host/";
$headers = array("Host: $host");
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
Do this instead:
$host = "www.example.com";
$url = "http://$host/";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);

Using cURL, I needed to call a third-party script which was returning binary data as attachment to pass on retrieved data again as attachment.
Problem was that the third-party script occassionally returned HTTP errors and I wanted to avoid passing on zero-length attachment in such case.
Combination of using CURLOPT_FAILONERROR and CURLOPT_HEADERFUNCTION callback helped to process the third-party script HTTP errors neatly:
<?php
function curlHeaderCallback($resURL, $strHeader) {
if (preg_match('/^HTTP/i', $strHeader)) {
header($strHeader);
header('Content-Disposition: attachment; filename="file-name.zip"');
}
return strlen($strHeader);
}
$strURL = 'http://www.example.com/script-whichs-dumps-binary-attachment.php';
$resURL = curl_init();
curl_setopt($resURL, CURLOPT_URL, $strURL);
curl_setopt($resURL, CURLOPT_BINARYTRANSFER, 1);
curl_setopt($resURL, CURLOPT_HEADERFUNCTION, 'curlHeaderCallback');
curl_setopt($resURL, CURLOPT_FAILONERROR, 1);
curl_exec ($resURL);
$intReturnCode = curl_getinfo($resURL, CURLINFO_HTTP_CODE);
curl_close ($resURL);
if ($intReturnCode != 200) {
print 'was error: ' . $intReturnCode;

If you specify a CAINFO, note that the file must be in PEM format! (If not, it won't work).
Using Openssl you can use:
openssl x509 -in <cert> -inform d -outform PEM -out cert.pem
To create a pem formatted certificate from a binary certificate (the one you get if you download the ca somewhere).

A bit more documentation (without minimum version numbers):
- CURLOPT_WRITEFUNCTION
- CURLOPT_HEADERFUNCTION
Pass a function which will be called to write data or headers respectively. The callback function prototype:
long write_callback (resource ch, string data)
The ch argument is CURL session handle. The data argument is data received. Note that its size is variable. When writing data, as much data as possible will be returned in all invokes. When writing headers, exactly one complete header line is returned for better parsing.
The function must return number of bytes actually taken care of. If that amount differs from the amount passed to this function, an error will occur.
- CURLOPT_READFUNCTION
Pass a function which will be called to read data. The callback function prototype:
string read_callback (resource ch, resource fd, long length)
The ch argument is CURL session handle. The fd argument is file descriptor passed to CURL by CURLOPT_INFILE option. The length argument is maximum length which can be returned.
The function must return string containing the data which were read. If length of the data is more than maximum length, it will be truncated to maximum length. Returning anything else than a string means an EOF.
[Note: there is more callbacks implemented in current cURL library but they aren't unfortunately implemented in php curl interface yet.]

beware that not all cURLlib constants are supported under php :
e.g. CURLOPT_PROGRESSFUNCTION or CURLOPT_WRITEDATA are not supported.
CURLOPT_WRITEFUNCTION, although undocumented is supported. It takes the name of a user_defined function.
the function should take two arguments (the curl handle, and the inputdata) and return the length of the written data
e.g.
<?php
function myPoorProgressFunc($ch,$str){
global $fd;
$len = fwrite($fd,$str);
print("#");
return $len;
}
curl_setopt($ch,CURLOPT_WRITEFUNCTION,"myPoorProgressFunc");
?>
Also be aware that CURLOPT_WRITEFUNCTION does NOT take the CURLOPT_FILE as a parameter!
in curl lib it would take CURLOPT_WRITEDATA but this is not supported by php; that's why I use "global $fd;" in my exemple function.
CURLOPT_HEADERFUNCTION works the same, and is guaranteed to receive complete header lines as input!
Hope this helps

CURLOPT_HTTPHEADER is NOT like the -H command line switch. The command line switch adds or replaces headers (much like the header() line in PHP, but for HTTP clients instead of servers), but the curl extension will eliminate the headers cURL sends by default.
For instance, your Authorization, Host, Referer, Pragma, and Accept headers which are normally written by default or by other CURLOPT_*'s.
Also, it might seem intuitive that this should accept an array hash of header->values, but this is not the case. It accepts an array of strings of the format "Header: Value", much like the -H command-line switch.
Hope this helps,

curl_close($ch); //close curl handle
?>
p.s. Make sure that there're no new lines before and after code or script may not work.

Force Curl Request To Go To A Particular IP Address
Yes, there is a method of passing an IP address to curl. Excellent for services with multiple IP addresses and also to take DNS out of the equation for testing/debugging.
<?php
function fetch_page($url, $host_ip = NULL)
{
$ch = curl_init();
if (!is_null($host_ip))
{
$urldata = parse_url($url);
// Ensure we have the query too, if there is any...
if (!empty($urldata['query']))
$urldata['path'] .= "?".$urldata['query'];
// Specify the host (name) we want to fetch...
$headers = array("Host: ".$urldata['host']);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
// create the connecting url (with the hostname replaced by IP)
$url = $urldata['scheme']."://".$host_ip.$urldata['path'];
}
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec ($ch);
curl_close ($ch);
return $result;
}
?>

If you've got problems with connecting througth a proxy using php/apache/xampp. So if you get no result string from the exec function, try enabling the following options in apache.
...\xampp\apache\conf
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so
cURL seems to neet this modules.

If you change the post array to a string, PHP creates the post data successfully.
As a quick and dirty example of implementing this fix:
<?php
$ch = curl_init;
$url = 'http://www.example.com';
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
foreach ($postData as $var) if (strpos($var, '@') === 0) {
$postAsString = true;
}
if ($postAsString === true) {
$str = '';
foreach ($postData as $key => $val) {
$str .= '&' . $key . '=' . $val;
}
$postData = substr_replace($str, '', 0, 1);
}
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
curl_exec($ch);
?>

Some of you may noticed that curl is not transferring cookies between sequent calls to a host. This is because you must activate curl`s "cookie parser". That is achieved using an external file like this:
<?php
curl_setopt(CURLOPT_FILE, '/tmp/cookies_file');
?>
If you don`t need to read any cookies but you still want the "cookie parser" use the same code but with dummy file with no data like '/dev/null', that way curl is storing cookies internaly per curl_handle:
<?php
curl_setopt(CURLOPT_FILE, '/dev/null');
?>
[EDIT BY danbrown AT php DOT net: In a note dated 26-SEP-08, (adamplumb AT gmail DOT com) offered the following addendum:
[It] should really be CURLOPT_COOKIEFILE. I was bitten by this issue myself with code that previously worked for logging into a website and posting a form. However, at some point the code just stopped working, and I eventually found that I needed to set this option to /dev/null for it to work.

Resetting CURLOPT_FILE to STDOUT won't work by calling curl_setopt() with the STDOUT constant or a php://output stream handle (at least I get error messages when trying the code from phpnet at andywaite dot com). Instead, one can simply reset it as a side effect of CURLOPT_RETURNTRANSFER. Just say
<?php curl_setopt($this->curl,CURLOPT_RETURNTRANSFER,0); ?>
and following calls to curl_exec() will output to STDOUT again.

Hi!
I have found some information I am sure it could help lot of programmers when they want to connect with curl to any https website and they haven't a good or right CA Cert :)
I give you just one example It has resolved me 2 hours of my time looking for a solution.
It is simple, just if you get any error in the curl_exec (use curl_error(...) to see the error to trace it) add the next line and everything is solved:
(note: replace $ch with the right curl variable)
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
<?php
$ch = curl_init();
$res= curl_setopt ($ch, CURLOPT_URL,"https://yoururl/cgi");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt ($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "Idc=si&");
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
$xyz = curl_exec ($ch);
curl_close ($ch);
echo $xyz;
if ($xyz == NULL) {
echo "Error:<br>";
echo curl_errno($ch) . " - " . curl_error($ch) . "<br>";
}
?>
I hope this helps.

It's possible to take advantage of multiple URLs on the same host in one curl_exec transaction ... just use multiple instances of CURLOPT_URL.
Example:
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://example.com/a.html");
curl_setopt($ch, CURLOPT_URL, "http://example.com/b.html");
curl_setopt($ch, CURLOPT_URL, "http://example.com/c.html");
curl_exec($ch);
curl_close($ch);
?>
... the URLs appear to be hit in the same order they are entered. This takes advantage of cURL's Persistant Connection capability if all the URLs are on the same host!

CURLOPT_RETURNTRANSFER has the interesting behaviour of tacking a null char onto the end of the string. This null char is actually on the end of the php string, and can cause some odd results if you're not expecting it to be there.

Two things that I noted, one of which has been mentioned earlier, if you are connecting to an SSL site (https) and don't have the appropriate certificate, don't forget to set CURLOPT_SSL_VERIFYPEER as "false"... it's set to "true" by default. Scratched my head over 2 hours to figure this one out as I had a machine with an older version installed and everything worked fine without using this option on that one - but failed on other machines with newer versions.
Second very important thing, I've never had my scripts work (tried on various machines, multiple platforms) with a Relative path to a COOKIEJAR or COOKIEFILE. In my experience I HAVE to specify the absolute path and not the relative path.
Small script I wrote to connect to a page, gather all cookies into a jar, connect to another page to login, taking the cookiejar with you for authentication:
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_COOKIEJAR, "/Library/WebServer/Documents/tmp/cookieFileName");
curl_setopt($ch, CURLOPT_URL,"https://www.example.com/myaccount/start.asp");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
ob_start(); // Prevent output
curl_exec ($ch);
ob_end_clean(); // End preventing output
curl_close ($ch);
unset($ch);
$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "field1=".$f1."&field2=".$f2."&SomeFlag=True");
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_COOKIEFILE, "/Library/WebServer/Documents/tmp/cookieFileName");
curl_setopt($ch, CURLOPT_URL,"https://www.example.com/myaccount/Login.asp");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$result = curl_exec ($ch);
curl_close ($ch);
?>

I was having problems with Authorize.net and the SSL cert matching even after adding:
<?php
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
?>
What I found after a lot of stumbling was I needed to set VERIFYHOST to FALSE. So if you are still have a problem with Authorize.NET SSL and cURL add this:
<?php
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
?>
