Donate your wasted CPU cycles to Distributed.net (http://www.distributed.net) First of all, don't use $PHP_SELF when dealing with things as vital as a shopping cart. Use a form with a method of POST. Then, have the action go to a second script where you use $HTTP_POST_VARS to retrieve the variables and add the item, then emit a "Location:" header to bounce back to the original script.
