Use a SESSION to store the values you want to remember.

Again SESSION would be your friend here.
Think of it this way. The browser may pass data to the php program using
either POST or GET methods. PHP programs may pass data using the SESSION
to other PHP programs.
The 'short cut' of using PHP_SELF and the browser-passed variables is
just that - a short cut.
