One further suggestion. I know it's not free, but there's a book out there, "PHP Fast & Easy Web Development" by, in my opinion, one of the php geniuses of all time, Julie Meloni.
It really is worth, in my humble opinion, the $25. Or you can do what I've done many times: Bring a pencil and notepad to Fry's, grab the book and go to their cafe. Spend as much time as you want taking notes - nobody will bother you! Really! Just like the library back in University (that's where I went to hide - nobody ever thought I'd be there!).
