logout

Dude The code great ...
can u plz temme my how do i end this session....
in other words logout ...
i tried session_destroy()
and session_unset()

It gives me an error sayin object cannot be destroyed

Try this:

foreach ($_SESSION as $k=>$v)
{
unset($_SESSION[$k]);
}
session_destroy();

the correct way to logout:

// Unset all of the session variables.
$_SESSION = array();
// If it's desired to kill the session, also delete the session cookie.
// Note: This will destroy the session, and not just the session data!
if (isset($_COOKIE[session_name()])) {
setcookie(session_name(), '', time()-42000, '/');
}
// Finally, destroy the session.
session_destroy();

look in the phpmanual:
