(PHP) How to destroy the session cookie correctly?

Question

I\'m trying to correctly log out of an admin user. Here is my function:

function logout()
{
    $_SESSION = array(); //destroy all of the session variables

If you really want to cover all bases try doing:

setcookie (session_id(), "", time() - 3600);
session_destroy();
session_write_close();

That should prevent further access to the session data for the rest of PHP execution. The browser may still show the cookie being set however the $_SESSION super will be blank
