Why Won't My Session DIE already?!

[duckduckgoose]

I'm trying to destroy a session, and then, should the user visit the same page again, regenerate a new session with a different ID. I thought that if I destroyed a session, this is what would happen automatically. Wrong?

In any event, I've been trying to destroy my session in everyway imaginable with this code:

        setcookie(session_name(), '', time() - 3600, '/');
        setcookie(session_id(), '', time() - 3600, '/');  

        session_unregister($_SESSION['SID']);
        $_SESSION=array();
        unset($_SESSION); 
        session_write_close();
        session_destroy();

But everytime I revisit my initial form page, all of my data is still there. I'm not sure I understand why I can't destroy the session.

Can someone explain?

[help_wanted]

does the first line of your session destroy page have a session start call?

The destroy page must first call the session (session start) then destroy it.
