<a href="<?php echo $_SERVER['PHP_SELF']?>?_SESSION[switch]=0">off</a>
This *might* work, if you have session.auto_start set to ON, so that
the session is started before PHP processes the URL, and if you have
register_globals set to "ON"
But I doubt it, as that would be horrible security, because you really
do not want to allow users to pollute your $_SESSION data.
Plus, of course, if you're trying to get sessions turned on/off from
this, you'll have the session auto_start and then turn it off and
destroy it within the script if they ask for it to be off, rather than
have it actually not be turned on in the first place.
Work through what happens with your link and the session
construction/tear-down in slow-motion to see why you can't really do
this the simplistic way you are trying.
