I had a quick look around the Monastery and CPAN for something that would parse PHP and build some sort of a function structure and variable dictionary .. I have spent an enjoyable hour, but have turned up nothing obvious.
I'd like to use this tool against a mass of related PHP files in order to determine who calls what, which functions are in which modules, who includes what, and that type of information. The kind of stuff that is useful when trying to get a jump-start on understanding a web application.
If nothing exists, I may see what I can put together using Parse::RecDescent (I've been itching to find the right project for that module -- and the time).
