Recommend a php book

[Reeve of shinra]

I have a moderate amount of experience with php. I can read it and understand what the script is doing for the most part but I wanna brush up and become a better coder since reading it and tweaking isnt exactly the same as writing from scratch.

I was thinking of getting a book on php geared towards intermediate users but I was looking to see if anyone has any suggestions - especially books that would become a better coder for vb3.

Thanks
