Does something exist that I can point to my PHP project and it can look at all the files (or just the ones that I specify) and generate a diagram based on the objects and function calls? It would be a good way to verify that my design is actually being implimented :)

Background: I'm trying to build a PHP website using OO principles and while, so far, it is working I still have a ways to go and already the complexity is getting out of control. I mean, I understand basically what's going on but (and I don't think I'm alone here) it's really helpful to me if I can visualise the system at once and see the flow so I can optimise, remove unnecessary things and of course, build on the foundations. I could sit down with a pen&paper and draw it (and I have done that for parts) but if there was some program that would generate an image, it would be much simplier. Plus I could do it more often.

Teşekkürler :)
