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 — Configura múltiples opciones para una transferencia cURL
Descripción
bool curl_setopt_array
( resource
$ch
, array $options
)Configura multiples opciones para una sesión cURL. Esta función es muy útil para configurar gran cantidad de opciones cURL sin tener que llamar cada vez curl_setopt().
Parámetros
-
ch -
El recurso cURL devuelto por curl_init().
-
opciones -
Un array especificando que opciones a configurar y con que valores. Las keys deben contener constantes curl_setopt() válidas o sus integer equivalentes.
Valores devueltos
Devuelve TRUE si todas las opciones se configuraron satisfactoriamente. Si una
opción no se pudo configurar devolverá FALSE inmediatamente. Ignorando cualquier
otra opción en el array de opciones.
Ejemplos
Ejemplo #1 Iniciando una nueva sesión cURL y capturando una página web
<?php
// Crea un nuevo recurso cURL
$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($ch);
?>
Anterior a PHP 5.1.3 esta función puede ser simulada con:
Ejemplo #2 O nuestra implementación de curl_setopt_array()
<?php
if (!function_exists('curl_setopt_array')) {
function curl_setopt_array(&$ch, $curl_options)
{
foreach ($curl_options as $option => $value) {
if (!curl_setopt($ch, $option, $value)) {
return false;
}
}
return true;
}
}
?>
Notas
Nota:
Igual que curl_setopt(), si se pasa un array a
CURLOPT_POSTcodificará los datos como multipart/form-data, mientras que si pasa una cadena URL-encoded codificará los datos como 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);
// ...
?>
