ummm I'm not sure if there is a good book for complete "newbs". U need to already know the basics for most.
Before I started PHP, i learned: Q-basic, Visual Basic, Flash ActionScript, C++, HTML, Javascript, CSS, TI-Basic, SHTML, and some JSP and ASP. So Yeah, the books were pretty helpful for me since I knew what I was doing.
So, I recommend You take several beginners online tutorials before you get a book. Just search "PHP tutorials" on Yahoo or something.
Good luck.
