If you just need to be able to zap a session at a given time, use session_destroy(). If you want to completely end the session, here's a snippet copy/pasted straight out of the documentation:

// 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();
