Understand the Yii Framework's help solution

After learning about the Yii Framework, I created a simple website using the Yii Framework. the database is Mysql, and the index. php page displays some basic information in the database table. Q: I want to process the displayed data and display it on the page. I am not familiar with Yii, it is not clear which function in the view or model or controler should be modified. I hope to know more about the Yii Framework.

The general processing method in the framework is generally that view only processes data output, while the controller processes some related functions. The model processes some functions of database operations for convenient calls.
