Well it all depends on the passing methood and the server setup, but if as you say your passing the value as a cookie then by default it should be recreated on every page within the site as a variable of the same name as the cookie.

So if you set a cookie like so:

setcookie ("TestCookie", "Test Value");

Then it would be recreated as a variable as such:

$TestCookie

Or if your server doesn't do the auto variable creation thingy it will most likely still be avaliable through the global $HTTP_COOKIE_VARS[] array as such:

$HTTP_COOKIE_VARS["TestCookie"]
