To install the Yii framework, you need to configure PHP and Composer according to different operating systems. The specific steps are as follows: 1. You need to manually download PHP and configure environment variables on Windows, then install Composer, use commands to create a project and run a built-in server; 2. It is recommended to use Homebrew to install PHP and Composer, then create a project and start a development server; 3. Linux (such as Ubuntu) install PHP, extensions and Composer through apt, then create a project and deploy a formal environment with Apache or Nginx. The main differences between different systems are in the environment construction stage. Once PHP and Composer are ready, the subsequent processes are consistent. Note

In Yii applications, the controller directory is used to store the controller class that handles user requests. This directory is located in app/controllers/ by default, and each controller file ends with "Controller", such as SiteController.php; common tasks include processing form submissions, obtaining data from the model, passing variables to views, redirecting users, and returning JSON responses; subdirectories can be used when organizing controllers, avoiding too much business logic, keeping method focus, utilizing inheritance and clear naming. As the intermediate layer in MVC mode, the controller coordinates the model and view and maps the URL to the corresponding action method, such as /Site/about corresponding SiteController::
