First let me say, if you are new to PHP or programming in general, skip this book. This is not a how to or even a cookbook for simple concepts. To get the most from this book you need to have a firm grounding in programming.

He sets the tone for the rest of the interview right there, noting that most of the book is made up of little examples, helpful bits to fill a need rather than teaching you the basics (or more advanced features) of PHP as a language. Cal spotlights this kind of content by talking about the "binary tree implementation" section. Check out the rest of the review for the full story.
