The application request cycle of the YII framework is as shown in the following figure:
1. The user initiates a request to the entry script web/index.php.
2. The entry script loads the application configuration and creates an application instance to handle the request.
3. The application resolves the requested route through the request component.
4. The application creates a controller instance to handle the request.
5. The controller creates an action instance and executes the filter for the operation.
6. If any filter returns failure, the action is cancelled.
7. If all filters pass, the action will be executed.
8. The action will load a data model, perhaps from a database.
9. The action will render a view and provide the data model to it.
10. The rendering result is returned to the response component.
11. The response component sends the rendering result to the user's browser.
