How do i unset a session... ie the user has clicked a logout link.

With cookies I would set the cookie to a past time value

I read about unset() in the php manual, but it says do NOT use unset($_SESSION);

session_destroy() and you still have to unset the cookie I think.

apparently its a combination, as shown when I looked up session_destroy... thanks

for those who didn't know

Code: Select all

<?php
// Initialize the session.
// If you are using session_name("something"), don't forget it now!
session_start();

// 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();
?>
