Yeah great. Or you do something that's not an enormous security hole,
since cookies can be freely created and edited by the user.

Running PHP scripts without the context of an HTTP request is only
possible by using cronjob s or similar things.
So the only thing you can do is saving timestamps of last activity (NOT
IN COOKIES!) and look every minute or so if there are expired ones.

If you would tell us what you are planing to do, we could tell you why
you don't want to do that.
