I have many years experience programming and have been doing PHP for awhile. This book has lots of philosophy and not many concrete examples of advanced PHP technique.The section on objects is especially poor. It reads as if the authors don't understand OOP and the examples are extremely poor. (I have over ten years OOP analysis, design, and programming in numerous OO languages, so, I should know)I found myself wasting a lot of time playing with sample code that didn't work, was poorly written, and certainly didn't illustrate what was being discussed.The book is so poor, I wonder if those who wrote the good reviews actually read and used the book or just looked through it.
