L’esempio che vi mostro qui di seguito permette di eseguire un login tramite script.

 
$url = "http://www.somesite.com/members/";
 
$ch = curl_init();
 
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
 
// send the username and password
curl_setopt($ch, CURLOPT_USERPWD, "myusername:mypassword");
 
// if you allow redirections
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
// this lets cURL keep sending the username and password
// after being redirected
curl_setopt($ch, CURLOPT_UNRESTRICTED_AUTH, 1);
 
$output = curl_exec($ch);
 
curl_close($ch);
