Kae Verens has posted a review of a PHP-related book from APress Publishing, "Object-Oriented Programming in PHP5":

In short: a very good concise introduction to OOP. I'll be keeping this on my desk for a while. The language use is strange but the code examples and the spread of topics make up for that in spades. This book has a very broad scope, but is clear in the essentials. If you're looking for an introduction to Objected Oriented Programming in PHP, I'd recommend this one.

The review gets into a bit more detail on "The Good", "The Bad" and "The Ugly" of its contents including its intro to OOP in PHP (good), the assumption that OOP is better than other programming types (bad) and the poor structure of the book (the ugly).
