I have to work on the worst #PHP code I've ever seen. Just some facts for you:
* A file I'm trying to wrap my head around is 12000 (yes, it's twelve thousand) lines long;
* It has several classes in it, and some functions just in between;
* It has constructions like $array['item']['anotherItem']['yetAnotherItem'][['item', 'item']];
* Its indentation mode is tabs (yes, not all the code, just for some files);
* And variables (well, most of them) are in snake_case.
That's my current life, folks.
