The Yii Cookbook is a collection of Yii tutorials, each addressing a specific development task. Everyone with a Yii forum account can participate in creating or editing tutorial pages in the cookbook. Write now to share your knowledge about Yii with other people.
P.S. The Yii cookbook subsystem is written in Yii (this project site except the forum is also written in Yii). It took me about three hours in total, including design and coding. This is another example showing how efficient Yii is. It not only runs efficiently, but also helps you develop your applications efficiently.
