Re:PHP.net is great. (Score 1)

I still use php.net a ton for the nitty gritty of everything, but for 90% of it all, I found it sometimes tedious to deal with. If you want EVERYTHING, it's great. I dunno, in a way it inspired me to write a php book because I was spending too much time trying to figure out sprintf() because it's not very beginner friendly. Since I mentioned it, I'll post a link to the book blog and the creative commons pdf version (complete): phpreferencebook.com.

I also really like going to tizag.com for their tutorials and plain jane explanations.
