It is always good to validate all the variables that are given in the url and would cause an error if they are of wrong type. For example, if your page is products.php?id=123 then run settype($id, "integer") in the script, before getting the product info from the database. If the user enters a non-numeric value in the url -- either pasting it wrong or intentionally :) -- the $id will be set to zero and database query will have no errors. http://www.php.net/manual/en/function.settype.php
