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 (aka. 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 review 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 review of 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.
Qiang XueLead developer of the Yii framework
Yii framework is a rapidly growing PHP5 MVC framework often referred to as Rails for PHP. It has become a solid base for many exciting web applications such as Stay.com and Russia Today's meetfriends.rt.com and can be a good base for your developments. Yii is an object-oriented, high-performance, component-based PHP web application framework. Yii is pronounced as Yee and is an acronym for "Yes It Is!".

You will learn about implementing shortcuts using core features, creating your own reusable code base, using test-driven development, and many more topics that will escalate your knowledge in no time at all!
Yii 1.1 Application Development Cookbook will help you learn more about Yii framework and application development practices in general with demonstrations of shortcuts and information about dangerous things you should not do.
Grouped in 13 chapters, the recipes will assist you to write your applications exploiting Yii core functionality to its full potential. The chapters are generally independent of each other and you can start reading from the chapter you need most, whether it is "AJAX and jQuery", "Database, Active Record and Model Tricks" or "Extending Yii".

Preface
Yii is a very flexible and high-performance application development framework written in PHP. It helps building web applications from small ones to large-scale enterprise applications. The framework name stands for Yes It Is. This is often the accurate and most concise response to inquires from those new to Yii:
Is it fast? ... Is it secure? ... Is it professional? ... Is it right for my next project? ... The answer is Yes, it is!
This cookbook contains 13 independent chapters full of recipes that will show you how to use Yii efficiently. You will learn about the hidden framework gems, using core features, creating your own reusable code base, using test-driven development, and many more topics that will bring your knowledge to a new level!
What this book covers
Chapter 1, Under the Hood provides information about the most interesting Yii features hidden under the hood: events, import, autoloading, exceptions, component, and widget configuration, and more.
Chapter 2, Router, Controller, and Views is about handy things concerning the Yii URL router, controllers, and views: URL rules, external actions and controllers, view clips, decorators, and more.
Chapter 3, AJAX and jQuery focuses on the Yii's client side that is built with jQuery—the most widely used JavaScript library out there. It is very powerful and easy to learn and use. This chapter focuses on Yii-specific tricks rather than jQuery itself.
Chapter 4, Working with Forms. Yii makes working with forms a breeze and documentation on it is almost complete. Still, there are some areas that need clarification and examples. Some of the topics covered in this chapter are creating own validators and input widgets, uploading files, using, and customizing CAPTCHA.
Chapter 5, Testing Your Application covers both unit testing, functional testing, and generating code coverage reports. Recipes follow a test driven development approach. You will write tests for several small applications and then will implement functionality.
Chapter 6, Database, Active Record, and Model Tricks is about working with databases efficiently, when to use models and when not to, how to work with multiple databases, how to automatically pre-process Active Record fields, and how to use powerful database criteria.
Chapter 7, Using Zii Components covers data providers, grids, and lists: How to configure sorting and search, how to use grids with multiple related models, how to create your own column types, and more.
Chapter 8, Extending Yii shows not only how to implement your own Yii extension but also how to make your extension reusable and useful for the community. In addition, we will focus on many things you should do to make your extension as efficient as possible.
Chapter 9, Error Handling, Debugging, and Logging reviews logging, analyzing the exception stack trace, and own error handler implementation.
Chapter 10, Security provides information about keeping your application secure according to the general web application security principle "filter input escape output". We will cover topics such as creating your own controller filters, preventing XSS, CSRF, and SQL injections, escaping output, and using role-based access control.
Chapter 11, Performance Tuning shows how to configure Yii to gain extra performance. You will learn a few best practices of developing an application that will run smoothly until you have very high loads.
Chapter 12, Using External Code focuses on using the third party code with Yii. We will use Zend Framework, Kohana, and PEAR but you will be able to use any code after learning how it works.
Chapter 13, Deployment covers various tips that are especially useful on application deployment, when developing an application in a team, or when you just want to make your development environment more comfortable.

Chapter 1. Under the Hood
In this chapter, we will cover:
Introduction
In this chapter, we will cover the most interesting Yii features that are hidden "under the hood". These are mostly described in the framework API, but since they are not mentioned in the official guide (http://www.yiiframework.com/doc/guide/) or mentioned very briefly, only experienced Yii developers usually use these. Yet, features described here are relatively simple and using them makes development with Yii much more fun and productive.
