Find user defined functions and their usage in a massive code base

Question

Hi,

I'm currently working with an massive PHP codebase, witch is completely undocumented.

Here's the deal. All of the PHP code is included every page call. They build a simple include all kinda function that scan's the directory and includes all PHP files it can find. It works recursively for all the subfolders.

I would like to know what functions are used in what files and from which files those functions came.

I need to know this in order to switch to normale includes. Also it gives me more information about not used functions and files (since it a really old and big codebase, there is a lot of legacy in it).

It there a tool or something for PHP that can check this kind of stuff in a codebase?

NetBeans gives me pretty good visibility, for the spot inquiry. I'm interested to see if you get something with more value as a straight "audit" or inventory tool.
