curl-setopt()
CURLOPT_ABSTRACT_UNIX_SOCKET
(int)
|
Enables the use of an abstract Unix domain socket instead of
establishing a TCP connection to a host and sets the path to
the given string. This option shares the same semantics
as CURLOPT_UNIX_SOCKET_PATH . These two options
share the same storage and therefore only one of them can be set
per handle.
Available as of PHP 7.3.0 and cURL 7.53.0
|
CURLOPT_ACCEPT_ENCODING
(int)
|
Sets a string with the contents
of the Accept-Encoding: header sent in an HTTP request.
Set to null to disable sending the Accept-Encoding: header.
Defaults to null .
Available as of cURL 7.21.6.
|
CURLOPT_ACCEPTTIMEOUT_MS
(int)
|
The maximum number of milliseconds to wait for a server
to connect back to cURL when an active FTP connection is used.
This option accepts any value that can be cast to a valid int.
Defaults to 60000 milliseconds.
Available as of cURL 7.24.0.
|
CURLOPT_ADDRESS_SCOPE
(int)
|
The scope id value to use when connecting to IPv6 addresses.
This option accepts any value that can be cast to a valid int.
Defaults to 0 .
Available as of cURL 7.19.0.
|
CURLOPT_ALTSVC
(int)
|
Pass the filename for cURL to use as the Alt-Svc cache file to read existing cache contents from and
possibly also write it back to a after a transfer, unless CURLALTSVC_READONLYFILE
is set via CURLOPT_ALTSVC_CTRL .
Available as of PHP 8.2.0 and cURL 7.64.1.
|
CURLOPT_ALTSVC_CTRL
(int)
|
Populate the bitmask with the correct set of features to instruct cURL how to handle Alt-Svc for the
transfers using this handle. cURL only accepts Alt-Svc headers over HTTPS. It will also only complete
a request to an alternative origin if that origin is properly hosted over HTTPS.
Setting any bit will enable the alt-svc engine. The options are:
CURLALTSVC_H1 ,
CURLALTSVC_H2 ,
CURLALTSVC_H3 , and
CURLALTSVC_READONLYFILE .
Available as of PHP 8.2.0 and cURL 7.64.1.

to append to the remote file instead of overwriting it.
Defaults to 0 .
Available as of cURL 7.17.0.
|
CURLOPT_AUTOREFERER
(int)
|
true to automatically set the Referer: field in
requests where it follows a Location: redirect.

this request will be fulfilled, however.
Available as of cURL 7.10.
|
CURLOPT_CAINFO
(int)
|
The name of a file holding one or more certificates to verify the
peer with. This only makes sense when used in combination with
CURLOPT_SSL_VERIFYPEER . Might require an absolute path.
|
CURLOPT_CAINFO_BLOB
(int)
|
The name of a PEM file holding one or more certificates to verify the
peer with. This option overrides CURLOPT_CAINFO .
Available as of PHP 8.2.0 and cURL 7.77.0

|
The number of seconds to wait while trying to connect. Use 0 to
wait indefinitely.
|
CURLOPT_CONNECTTIMEOUT_MS
(int)
|

portion of the connect will still use full-second resolution for
timeouts with a minimum timeout allowed of one second. Available as of cURL 7.16.2.
|
CURLOPT_CONNECT_ONLY
(int)
|
true tells the library to perform all the required proxy authentication
and connection setup, but no data transfer. This option is implemented for
HTTP, SMTP and POP3.
Available as of cURL 7.15.2.
|
CURLOPT_CONNECT_TO
(int)
|
Connect to a specific host and port instead of the URL's host and port.
Accepts an array of strings with the format
HOST:PORT:CONNECT-TO-HOST:CONNECT-TO-PORT .
Available as of PHP 7.0.7 and cURL 7.49.0
|
CURLOPT_COOKIE
(int)
|

used in the HTTP request.
Note that multiple cookies are separated with a semicolon followed
by a space (e.g., "fruit=apple; colour=red ")
|
CURLOPT_COOKIEFILE
(int)
|
The name of the file containing the cookie data. The cookie file can
be in Netscape format, or just plain HTTP-style headers dumped into
a file.
If the name is an empty string, no cookies are loaded, but cookie
handling is still enabled.
|
CURLOPT_COOKIEJAR
(int)
|
The name of a file to save all internal cookies to when the
handle's destructor is called.
Uyarı
As of PHP 8.0.0, curl_close() is a no-op
and does not destroy the handle.
If cookies need to be written prior to the handle being automatically
destroyed, call unset() on the handle.
|
CURLOPT_COOKIELIST
(int)
|
A cookie string (i.e. a single line in Netscape/Mozilla format, or a regular
HTTP-style Set-Cookie header) adds that single cookie to the internal cookie store.
"ALL" erases all cookies held in memory.
"SESS" erases all session cookies held in memory.
"FLUSH" writes all known cookies to the file specified by CURLOPT_COOKIEJAR .
"RELOAD" loads all cookies from the files specified by CURLOPT_COOKIEFILE .
Available as of cURL 7.14.1
|
CURLOPT_COOKIESESSION
(int)
|
true to mark this as a new cookie "session". It will force libcurl
to ignore all cookies it is about to load that are "session cookies"
from the previous session. By default, libcurl always stores and
loads all cookies, independent if they are session cookies or not.
Session cookies are cookies without expiry date and they are meant
to be alive and existing for this "session" only.
|
CURLOPT_CRLF
(int)
|
true to convert Unix newlines to CRLF newlines
on transfers.
|
CURLOPT_CRLFILE
(int)
|
Pass a string naming a file with the concatenation of
CRL (Certificate Revocation List) (in PEM format)
to use in the certificate validation that occurs during the SSL exchange.
When cURL is built to use GnuTLS,
there is no way to influence the use of CRL passed
to help in the verification process.
When cURL is built with OpenSSL support,
X509_V_FLAG_CRL_CHECK
and X509_V_FLAG_CRL_CHECK_ALL are both set,
requiring CRL check against all the elements of the certificate chain
if a CRL file is passed.
Also note that CURLOPT_CRLFILE implies
CURLSSLOPT_NO_PARTIALCHAIN
as of cURL 7.71.0 due to an OpenSSL bug.
Available as of cURL 7.19.0
|
CURLOPT_CUSTOMREQUEST
(int)
|
A custom request method to use instead of
"GET" or "HEAD" when doing
a HTTP request. This is useful for doing
"DELETE" or other, more obscure HTTP requests.
Valid values are things like "GET" ,
"POST" , "CONNECT" and so on;
i.e. Do not enter a whole HTTP request line here. For instance,
entering "GET /index.html HTTP/1.0\r\n\r\n"
would be incorrect.
Bilginize:
Don't do this without making sure the server supports the custom
request method first.
|
CURLOPT_DEFAULT_PROTOCOL

|
The default protocol to use if the URL is missing a scheme name.
Available as of PHP 7.0.7 and cURL 7.45.0
|
CURLOPT_DIRLISTONLY
(int)
|
Setting this option to 1 will have different effects
based on the protocol it is used with.
FTP and SFTP based URLs will list only the names of files in a directory.
POP3 will list the email message or messages on the POP3 server.
For FILE, this option has no effect
as directories are always listed in this mode.
Using this option with CURLOPT_WILDCARDMATCH
will prevent the latter from having any effect.
Defaults to 0 .
Available as of cURL 7.17.0.
|
CURLOPT_DISALLOW_USERNAME_IN_URL

Available as of cURL 7.24.0
|
CURLOPT_DNS_SHUFFLE_ADDRESSES
(int)
|

|
CURLOPT_MAX_SEND_SPEED_LARGE
