As a recently qualified Zend Certified Engineer I spent many an hour pouring through this book as part of my exam revision. The book is a relatively slim affair, the page count equalling that of only a few chapters in most other study guides, such as the Microsoft, Cisco or Novell examination publications. This is somewhat of a double-edged sword '" on the plus side it means it will not take you very long to read through it. On the down side it means if you're quite new to PHP and are reading this book in isolation, you'll be left thinking "huh?" a number of times.

He gives a structure of the book, its chapters and how those are broken down as well. He makes a very important point about the book too - it's not a "learning PHP" book at all. It's very much for those wanting to move to that next level. Overall, he seems to think the book is a good resource for those looking to take the exam, but does find some of the content (or lack there of) a bit frustrating at times...
