proper way to logout from a session in PHP

Question

I have read many php tutorials for logout scripts, i am wondering what could be the proper way to logout from a session!

Script 1

Answer 1

Personally, I do the following:

session_start();
setcookie(session_name(), '', 100);
session_unset();
session_destroy();
$_SESSION = array();

That way, it kills the cookie, destroys all data stored internally, and destroys the current instance of the session information (which is ignored by session_destroy).
