Depends on what you want...,
This review is from: PHP: Your visual blueprint for creating open source, server-side content (Paperback)
If you are a beginner to programming languages this book is very good. If you are a proffesional this is a book that you would breeze through in a night, maybe two to get an overview of the language.
The book is good for a beginner because you cannot get more detailed about the small topic chunks they covered at any given time. The books assumes you know nothing or virtually nothing of programming languages or server side scripting.
The book is only a wet your lips kind of thing for a proffessional. It will not give you everything you need to really write good production sites. You need another book for that. Even though it only wets your lips, this book is a good book even for the proffesional because it is a very quick read for someone who knows other programming languages.
