Provides a complete, practical guide for both the experienced programmer who is considering PHP for the first time and the current PHP user looking to fully exploit its new capabilities, starting with a detailed summary of the basics and moving quickly on to more advanced topics. Original. (Intermediate)
Might work as a reference book (it's big enough!) but not all that helpful. Dances back and forth between really basic and really complex. The examples are pretty lame, but at least they are real-world.
