I have one page session.php and my code is:
 @session_start();
            if(!isset($_SESSION['uname']) || $_SESSION['uname'] == " " || !isset($_SESSION['uid']) || $_SESSION['uid'] == " ")
                   {
                echo "<script language='javascript'>";
                echo "window.location='../index.php'";
                echo "</script> ";
                exit;           
            }
And I also want to edit session timeout function this code is:
$_SESSION['start'] = time(); // taking now logged in time
        $_SESSION['expire'] = $_SESSION['start'] + (1* 10) ; // ending a session in 30 seconds
            $now = time(); // checking the time now when home page starts
            if($now > $_SESSION['expire'])
            {
                session_destroy();
                echo "Your session has expire !  <a href='logout.php'>Click Here to Login</a>";
            }
            else
            {
                echo "This should be expired in 1 min <a href='logout.php'>Click Here to Login</a>";
            }
But this code is not working so help me how can I set session time out in session.php page.
Thank You..
