Jonathan Street has posted a review of a book from Quentin Zervaas - "Practical Web 2.0 Applications with PHP".

If you are already comfortable taking a project from concept to a working application this book will have little for you. If you are comfortable working with PHP, able to put together standalone tools and pages, perhaps develop a wordpress plugin but have not yet created a complete site from scratch then this may be the book that helps you "step up a gear".

He mentions the application that he book helps you develop (a blogging platform) and goes through a summary of each chapter with opinions on each. He also points to a sample chapter if you'd like an idea of what the book is like.
