getting a list of all php functions

Okay, my goal is to compile an array of *all* functions currently defined and available in PHP 4.1.1. That's a simple task if all I want is functions for the extensions I chose to compile into PHP (get_defined_functions()), but what about the other ones? Is there a place somewhere that has a text file that I can just read line-by-line or perhaps comma separated? Or maybe a version of PHP I can download which has all extensions built in?
