in reply to 'use strict' is not Perl

One thing that hasn't been pointed out yet is in PHP, variables are private by default inside functions; you have to explicitly declare them as global for the rest of the program to access them. This means that you're effectively "using (a small part of) strict" inside functions. A small point, but I thought I'd post it for the sake of completeness.
