There are two approaches that come to mind. Constants created with define() cannot be modified or unset later. You could probably modify your code to look something like: define("USERID", $USER_INFO['userid']); (Note the lack of a dollar sign in front of a constant.) Alternately, you could toss the entire thing into a class and have your developers call class methods (e.g. getUserID()). If define() works, however, I can't see why you'd want to use a class.
