curl_multi_select
it should be noted that when using CURLOPT_POSTFIELDS in a loop, CURLOPT_POSTFIELDS appends to the sting. You can use unset() if you don't want this sort of behavior.
<?php
//this will append postfields
while(true) {
$options = array(CURLOPT_POSTFIELDS => 'foo=bar&foo2=bar');
$ch = curl_init("http://www.example.com");
curl_setopt_array($ch, $options);
curl_exec($ch);
curl_close($ch);
}
//this will NOT append postfields
while(true) {
$options = array(CURLOPT_POSTFIELDS => 'foo=bar&foo2=bar');
$ch = curl_init("http://www.example.com");
curl_setopt_array($ch, $options);
curl_exec($ch);
curl_close($ch);
unset($options[CURLOPT_POSTFIELDS]);
}
?>
curl_setopt_array
(PHP 5 >= 5.1.3)
curl_setopt_array — Set multiple options for a cURL transfer
Descrição
bool curl_setopt_array
( resource $ch
, array $options
)
Define múltiplas opções para um sessão cURL. Esta função é útil para definir diversas opções cURL sem repetir a chamada da função curl_setopt().
Parâmetros
- ch
-
Um manipulador cURL retornado por curl_init().
- options
-
Um array especificando quais opções serão definida e seus respectivos valores. As chaves devem ser válidas constantes curl_setopt() ou seu inteiros equivalentes.
Valor Retornado
Retorna TRUE se todas opções foram definididas com sucesso. Se uma opção não foi definida com sucesso, FALSE é imediatamente retornado, ignorando qualquer outra opção da array options.
Exemplos
Exemplo #1 Inicializando uma nova sessão cURL e obtendo o código-fonte de uma página web
<?php
// create a new cURL resource
$ch = curl_init();
// set URL and other appropriate options
$options = array(CURLOPT_URL => 'http://www.example.com/',
CURLOPT_HEADER => false
);
curl_setopt_array($ch, $options);
// grab URL and pass it to the browser
curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
?>
Antes do PHP 5.1.4 esta função pode ser simulada com:
Exemplo #2 Nossa implementação da curl_setopt_array()
<?php
if (!function_exists('curl_setopt_array')) {
function curl_setopt_array(&$ch, $curl_options)
{
foreach ($curl_options as $option => $value) {
if (!curl_setopt($ch, $option, $value)) {
return false;
}
}
return true;
}
}
?>

Starting in PHP 5.2.0, CURLOPT_FOLLOWLOCATION can't be set via curl_setopt_array() (or curl_setopt()) when either safe_mode is enabled or open_basedir is set. In these cases, the order of CURLOPT_* settings in the array can be important.

In case that you need to read SSL page content from https with curl, this function can help you:
<?php
function get_web_page( $url,$curl_data )
{
$options = array(
CURLOPT_RETURNTRANSFER => true, // return web page
CURLOPT_HEADER => false, // don't return headers
CURLOPT_FOLLOWLOCATION => true, // follow redirects
CURLOPT_ENCODING => "", // handle all encodings
CURLOPT_USERAGENT => "spider", // who am i
CURLOPT_AUTOREFERER => true, // set referer on redirect
CURLOPT_CONNECTTIMEOUT => 120, // timeout on connect
CURLOPT_TIMEOUT => 120, // timeout on response
CURLOPT_MAXREDIRS => 10, // stop after 10 redirects
CURLOPT_POST => 1, // i am sending post data
CURLOPT_POSTFIELDS => $curl_data, // this are my post vars
CURLOPT_SSL_VERIFYHOST => 0, // don't verify ssl
CURLOPT_SSL_VERIFYPEER => false, //
CURLOPT_VERBOSE => 1 //
);
$ch = curl_init($url);
curl_setopt_array($ch,$options);
$content = curl_exec($ch);
$err = curl_errno($ch);
$errmsg = curl_error($ch) ;
$header = curl_getinfo($ch);
curl_close($ch);
// $header['errno'] = $err;
// $header['errmsg'] = $errmsg;
// $header['content'] = $content;
return $header;
}
$curl_data = "var1=60&var2=test";
$url = "https://www.example.com";
$response = get_web_page($url,$curl_data);
print '<pre>';
print_r($response);
?>

There is no CURLOPT_MAXFILESIZE in the PHP module but it's function only works with Content-Length headers anyway. There are two ways of checking download sizes, one is after the download is complete using filesize(), the other is as the download is running allowing you to terminate before wasting time and disk space.
<?php
$GLOBALS['file_size'] = 0;
$GLOBALS['max_file_size'] = 1024 * 1024;
function on_curl_header($ch, $header)
{
$trimmed = rtrim($header);
if (preg_match('/^Content-Length: (\d+)$/', $trimmed, $matches))
{
$file_size = $matches[1];
if ($file_size > $GLOBALS['max_file_size']) {
// handle error here.
}
}
return strlen($header);
}
function on_curl_write($ch, $data)
{
$bytes = strlen($data);
$GLOBALS['file_size'] += $bytes;
if ($GLOBALS['file_size'] > $GLOBALS['max_file_size']) {
// handle error here.
}
return $bytes;
}
$ch = curl_init();
$options = array(CURLOPT_URL => 'http://www.php.net/',
CURLOPT_HEADER => false,
CURLOPT_HEADERFUNCTION => 'on_curl_header',
CURLOPT_WRITEFUNCTION => 'on_curl_write');
curl_setopt_array($ch, $options);
curl_exec($ch);
// ...
?>

You can use CURLOPT_HEADERFUNCTION with a callback inside an object. This makes is it easy to capture the headers for later use. For example:
<?php
class Test
{
public $headers;
//...
public function exec($opts)
{
$this->headers = array();
$opts[CURLOPT_HEADERFUNCTION] = array($this, '_setHeader');
$ch = curl_init();
curl_setopt_array($ch, $opts);
return curl_exec($ch);
}
private function _setHeader($ch, $header)
{
$this->headers[] = $header;
return strlen($header);
}
}
$test = new Test();
$opts = array(
//... your curl opts here
);
$data = $test->exec($opts);
print_r($test->headers);
?>
...something like that
(This works in php v. 5.1.4)
