Curl mediafire

[fedemarkco]

Agregué el parámetro submit_login pero sigue igual:

$login_email = "myuser";
$login_pass = "mypass";
$cookies = getcwd() . "/cookies.txt";
$login_submit = "Login to MediaFire";




$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, 'http://www.mediafire.com/dynamic/login.php');
curl_setopt($curl, CURLOPT_POSTFIELDS, 'login_email=' . urlencode($login_email) . '&login_pass=' . urlencode($login_pass). '&submit_login=' . urlencode($login_submit));
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_COOKIEJAR, $cookies);
curl_setopt($curl, CURLOPT_COOKIEFILE, $cookies);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/530.5 (KHTML, like Gecko) Chrome/2.0.172.39 Safari/530.5');
echo curl_exec($curl);
