Hi, in trying to learn php I like to look at other open source code. Is there a utility that will cross reference php programs. Output: where functions are defined and used, where objects are defined and used and variables defined and used. Makes it a lot easier to get my head around software. I'm sure this must exist I just haven't been able to locate an open source version or any other version for that matter. TIA RR
Thanks for that. It is what I had in mind. Now I'll have to see if it works on my Mac. Funny I have search sourceforge for this and never found anything under cross reference.
