When Alex told me he was about to write a Yii cookbook about a year ago, I was wondering how original it would be, considering the fact that there was already an online user-contributed cookbook (also known as Yii wiki). It turned out Alex produced a book that is not only full of wisdom about how to use Yii effectively, but also presented in such a systematic way that it can be taken as an essential companion book to the definitive guide to Yii. In fact, Alex has successfully intrigued the interest of every member in the Yii developer team when he asked for reviews and comments on his newly finished book chapters.
As the founder and the lead developer of the Yii framework, I feel this book is a must-read for every Yii programmer. While this book does not describe directly the rules set by Yii, it shows how to program with Yii from a practical perspective. People who are driven by tight project schedules will find this book very handy, as it gives ready-to-use solutions to many problems they may face in their projects. People who are already familiar with Yii will also find this book very informative as most problem solutions given in the book can be considered as officially recommended because they have undergone thorough a review by every Yii developer team member. Alex, through this book and his active participation in the Yii project, proved himself to be a great programmer, as well as a good writer.
