What is the purpose of the views directory in Yii?

In Yii, the view directory (views) is used to store all PHP files responsible for rendering the user interface. It acts as a display layer of the application, separating logic from layout. Each controller corresponds to a folder under views, and each action corresponds to a view file. For example, SiteController's actionIndex() will render views/site/index.php; when $this->render() is called, Yii will automatically find the corresponding view file according to the naming specification, and can pass data through the second parameter; developers can also customize the view path by modifying viewPath or rewriting getViewPath(); in addition, view

Laravel MVC: quickstart guide

Laravel was chosen for its elegant syntax, powerful features and MVC architecture. 1) The MVC mode separates data (model), logical flow (controller) and presentation (view), improving the maintainability and scalability of the code. 2) Shows how the model, controller and view work together through code examples. 3) It is recommended to keep the model strong, the controller is concise, and the view focuses on display. 4) Laravel's routing system is flexible and can be mapped directly to the controller. 5) Use preload to optimize query performance to avoid N 1 query problems. 6) Follow the DRY principle, reuse code using Blade templates and EloquentORM to maintain consistency and simplicity.
