I have several variables that I set in a session - to record that a user is logged in.
I want to be able to unset them - when they log out.

        $_SESSION['PERMS_USER'] = 'fred';
Sets the variable quite nicely, I can also change it and the change is recorded.
I cannot unset it. I have tried (in various combinations):

        unset($_SESSION['PERMS_USER']);
        unset($HTTP_SESSION_VARS['PERMS_USER']);
        session_unregister($SESSION['PERMS_USER']);
        session_unregister($HTTP_SESSION_VARS['PERMS_USER']);

None of which have any effect.

What should I do ?

Thanks

Merry Christmas.
