I started reading the book because I'm working in PHP a little but am "self-taught" on it. I wanted something like Crockford's similarly titled JavaScript: The Good Parts, to cover both the basics of PHP that I may not have encountered in my self-taught tinkering, as well as the "cool tricks" that seasoned developers have learned.
I was disappointed to find that this book contained neither. Even the basics covered are
extremely basic at BEST. I got to the section on "getters and setters," which, instead of covering the get and set magic methods that let you define actual OOP style getters and setters, the author describes adding methods that just happen to be called setx and getx and have no link to a property x other than name. Bizarre.
From there I skipped back to the chapter at the end titled "advanced goodness," only to find even more very basic stuff covered under the guise of "advanced" - i.e. regex, SimpleXML, and *gasp* IDEs and popular PHP sites.
I'll be hitting PHP Hacks, and the PHP Cookbook next, both ALSO from O'Reilly. Hopefully one or both of them will reflect the quality that I NORMALLY associate with the publisher...
