Hi!
Welcome to the list!

One other option you can try is writing the value into a session cookie. IIRC 
if you set the cookie to expire in the past then it will get dropped by the 
browser as soon as the current session ends. Session support is very easy to 
use in PHP. See here
http://us3.php.net/manual/en/ref.session.php

Hope this helps.
