There are penetration testing tools, and these are pretty easy to write 

Analyzing code is more challenging than it sounds, because your task 
winds up being a substantial subset of what a code parser does - you 
have to be able to reliably interpret code and what it does, tracking 
data the entire time, and making educated guesses about potential 
safeguards. There are some recent PHP extensions written by Sara Golemon 
that can help, but it's still a very non-trivial task.

I do a fair number of PHP security audits, and most of my process still 
revolves around a manual inspection of the code.
