curl_reset
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);
?>
curl_setopt_array
(PHP 5 >= 5.1.3)
curl_setopt_array — Fixe plusieurs options pour un transfert cURL
Description
bool curl_setopt_array
( resource
$ch
, array $options
)Fixe plusieurs options pour une session cURL. Cette fonction est utile pour configurer un grand nombre d'options cURL sans appeler à chaque fois curl_setopt().
Liste de paramètres
-
ch -
Un gestionnaire cURL retourné par la fonction curl_init().
-
options -
Un tableau spécifiant quelles options à fixer avec leurs valeurs. Les clés devraient être des constantes valides de curl_setopt() ou leur entier équivalent.
Valeurs de retour
Retourne TRUE si toutes les options ont été fixées correctement. Si une
option ne peut pas être fixée correctement, FALSE est retourné
immédiatement, en ignorant toutes les options futures dans le tableau
options.
Exemples
Exemple #1 Initialisation d'une nouvelle session cURL et récupération d'une page web
<?php
// crée une nouvelle ressource cURL
$ch = curl_init();
// fixe l'URL et les autres options appropriées
$options = array(CURLOPT_URL => 'http://www.example.com/',
CURLOPT_HEADER => false
);
curl_setopt_array($ch, $options);
// attrape l'URL et la passe au navigateur
curl_exec($ch);
// ferme la ressource cURL et libère les ressources systèmes
curl_close($ch);
?>
Avant PHP 5.1.3, cette fonction peut être simulée avec :
Exemple #2 Notre propre implémentation de la fonction curl_setopt_array()
<?php
if (!function_exists('curl_setopt_array')) {
function curl_setopt_array(&$ch, $curl_options)
{
foreach ($curl_options as $option => $value) {
if (!curl_setopt($ch, $option, $value)) {
return false;
}
}
return true;
}
}
?>
Notes
Note:
Avec la fonction curl_setopt(), le fait de passer un tableau comme valeur de la constante
CURLOPT_POSTfera que les données seront encodées comme multipart/form-data, tandis que le fait de passer une chaîne encodée URL fera que les données seront encodées comme application/x-www-form-urlencoded.

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.

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]);
}
?>

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)

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);
// ...
?>
