Sorry if this is a bad place to post this but i figured i would get the best answers from people in here.

What is the best book to read and learn PHP? I know a but of php now but i would love to learn more or get better at what i do know.

I am currently reading Simply SQL and i love it, the teaching is perfect for me. Not to confusing but not like reading a children book and every thing is explained out nicely. I want this kind of book but on the PHP subject.

Any suggestions?
