Can't log out

[subnet_rx]

I'm using sessions and a logout.php page when the person wants to log out. Here's the code:

  session_start();
  require_once('globalsettings.inc.php');
  require_once('functions.inc.php');
  logout();
    
  // reroute to calendar home page
  redirect2URL("index.php");
  exit; 

The logout function simply does this:

    function logout() {
        unset($_SESSION["AUTH_USERID"]);
        unset($_SESSION["AUTH_SPONSORID"]);
        unset($_SESSION["AUTH_SPONSORNAME"]);
        unset($_SESSION["AUTH_ADMIN"]);
    } 

This is not working in IE or FF though, and I never get logged out. What is going wrong?

How do you determine whether a user is logged in or not?

[Servyces]

Thy this

<?php
function logout() {
        if(isset(session_id())) {
            unset($_SESSION["AUTH_USERID"]);
            unset($_SESSION["AUTH_SPONSORID"]);
            unset($_SESSION["AUTH_SPONSORNAME"]);
            unset($_SESSION["AUTH_ADMIN"]);
            session_destroy();
        } 
}
?>

What's the logic behind unsetting 4 _SESSION variables, then destorying the session?

[subnet_rx]

session_destroy just kept logging me out after I made a certain choice after logging in. I'm not creating my own program, this is a calendar program that is supposed to be a great product, but it hasn't been updated since 2005. So, I can only assume that I can't log out because of my browser (FF 2.0 and IE 7) or because of my server environment (PHP 4.1.2). I'm just trying to fix it to work on our server. This is the first real problem that I have encountered though.
