$forum array... where?

[mdevour]

I'm trying to understand the code better before attempting a modification to the forumhome_forumbit_level1_nopost template.

Where does the $forum array variable come from? Where is it declared, initialized, assigned values, whatever? What is its scope? What does it contain?

As far as I can tell, the Code Documentation in the Members Area does not include an index by variable, so how else can I find information about them?

What is a better way to answer this question for myself, rather than asking random questions like this on the forum? I'm barely starting to understand PHP, so I don't know the tools or techniques yet. Please point me in the right direction!

Thanks!
