Proper use of session_set_cookie_params

Question

I am trying to implement a login system with the "remember me" function. This is my login page: http://pastebin.com/q6iK0Mgy . In this, I am trying to extend the session cookie expiration (PHPSESSIONID) using session_set_cookie_params (). But it does not work.

Relevant part of the code: In this case, the inner if () loop is executed, but session_set_cookie_params ('3600') has no effect. I call session_name (), as this should be a requirement for session_set_cookie_params () (according to one of the comments to the php manual)

if ( isset($_POST["submit"]) ) 
 {
     session_name() ;
     echo "calling before checked " ;
     if ( $_POST["remember"] == "on") 
    {
       // extend expiration date of cookie
       session_set_cookie_params('3600');
       echo "<br/>calling after sessions_set_cookie_params" ;
    }
 } 
 require_once("includes/session.php"); //session start ?>
