What are controllers in Yii, and what is their purpose?
In Yii, the controller coordinates application logic by processing user requests, interactive models, and rendering views. The main responsibilities of the controller include: ① Processing HTTP requests; ② Interacting with the model to obtain or save data; ③ Deciding which view to display and pass data; ④ Processing form submissions; ⑤ Returning HTML, JSON or redirection responses. Yii controllers are usually inherited from yii\web\Controller, and each public method corresponds to an action that can be accessed through the URL. For example, visiting http://example.com/site/index will call the actionIndex() method of SiteController. Common tasks include verification of input, calling models, and rendering

How do I log security events in Yii?
Recording security events in Yii can be achieved by configuring log targets, triggering key event logs, considering database storage, and avoiding recording sensitive information. The specific steps are as follows: 1. Set a dedicated log target in the configuration file, such as FileTarget or DbTarget, and specify the classification as 'security'; 2. Use Yii::info() or Yii::warning() to record the log when a critical security event (such as login failure and password reset) occurs; 3. Optionally store the logs in the database for query and analysis, and you need to create a table first and configure the logTable parameters; 4. Avoid including sensitive data, such as passwords or tokens when recording context information, and you can use parameter replacement to add IP and username; 5

How do I create a new controller in Yii?
Creating a controller in the Yii framework requires the naming, location and inheritance specifications. 1. Naming and location must be standardized: the controller class name ends with Controller, such as PostController, the main application is delegated to controllers/directory, and the module is placed in the controllers folder of the corresponding module; 2. Write the controller content: define the class and inherit yii\web\Controller (Web application) or yii\console\Controller (command line), such as namespaceapp\controllers;useyii\web\Controller;classPostContr

How do I use asset bundles in Yii?
Using Yii's assetbundles is a best practice for managing CSS and JS files. It defines resource groups centrally through PHP classes, and automatically handles dependencies, merging and caches. 1. The resource package is a PHP class used to organize CSS, JS and other resources and declare their dependencies; 2. Register resource packages in the view or layout to automatically generate HTML tags; 3. Different resource packages can be conditionally registered according to user role or page type; 4. The resource files are placed in web/css and web/js by default, and the path can be customized; 5. Use the assetManager configuration to add timestamps to achieve version control, solving browser caching problems. Correct use of resource packages can improve project structure clarity and loading efficiency

How do I render a view from a controller?
In the MVC framework, the mechanism for the controller to render views is based on the naming convention and allows explicit overwriting. If redirection is not explicitly indicated, the controller will automatically find a view file with the same name as the action for rendering. 1. Make sure that the view file exists and is named correctly. For example, the view path corresponding to the action show of the controller PostsController should be views/posts/show.html.erb or Views/Posts/Show.cshtml; 2. Use explicit rendering to specify different templates, such as render'custom_template' in Rails and view('posts.custom_template') in Laravel
