Studying the framework ¶

Start studying the MVC pattern. You will understand the roles of the model, the view and the controller and know where goes each part of the code.

• MVC on the Wikipedia
• MVC on the guide
• MVC on the exellent article Yii for Beginners

Read the guide. It is the most important step in learning Yii. A few tips:

• Click on the links throughout the guide, especially the links to the API documentation.
• Explore the API and click on "show" to see the code behind the methods.

Explore the API documentation. See the relationship of the classes, how they extend and are extended by each other and how they are organized in packages.

Very important classes (check them and their extended/extending classes throughly):

• YiiBase
• Yii
• CComponent
• CModule
• CApplication
• CWebApplication
• CController
• CModel
• CActiveRecord

Explore Yii's website. There you'll find:

• The demos.
• The extensions. You can browse by categories, by rating or by the number of downloads.
• The wiki (here!), a great source of information about the framework. You will find great articles when sorting by rating, by views, and by comments.
• The forum. A great resource to meet people and learn more about the framework. Create an account there and you'll be able to post your questions.

Then, you can start a fresh Web app project to do anything you want to learn the framework. I suggest that you read the framework's source files and follow the execution path of the methods you call. You'll learn a lot about how it works internally. This knowledge will prove very useful in the future, trust me.
