I'm not sure what in your code (running on the client's PC) you expect to cause the php script (running on the server) to run. You'll need to invoke the php by making some kind of http request (like get http://yoururl/recheckcookie.php).

Look up XMLHttpRequest or preferably the corresponding JQuery to see how to perform the HTTP request.
