The choice of Yii or Laravel depends on project requirements and team expertise. 1) Yii is suitable for high performance needs and has a lightweight structure. 2) Laravel provides rich functions, is developer-friendly and suitable for complex applications. Both are scalable, but Yii is easier to modular, while Laravel community is more resourceful.

beforeAction() is used in Yii2 to run logic before the controller action is executed. If permission checks or requests modification, it must return true or parent class call to continue execution; afterAction() is run after the action is executed and before the response is sent, which is suitable for output modification or logging. 1.beforeAction() is run before the action is executed, and can be used for user permission verification. For example, redirecting the unlogged user to the login page, you need to return parent::beforeAction($action) or true to continue the process, otherwise the action execution will be prevented; 2. You can skip the check of a specific action by checking $action->id; 3. AfterAc

Laravel's MVC architecture consists of a model, a view and a controller, which are responsible for data logic, user interface and request processing respectively. 1) Create a User model to define data structures and relationships. 2) UserController processes user requests, including listing, displaying and creating users. 3) The view uses the Blade template to display user data. This architecture improves code clarity and maintainability.

When saving data to the database in the Yii framework, it is mainly implemented through the ActiveRecord model. 1. Creating a new record requires instantiation of the model, loading the data and verifying it before saving; 2. Updating the record requires querying the existing data before assignment; 3. When using the load() method for batch assignment, security attributes must be marked in rules(); 4. When saving associated data, transactions should be used to ensure consistency. The specific steps include: instantiating the model and filling the data with load(), calling validate() verification, and finally performing save() persistence; when updating, first obtaining records and then assigning values; when sensitive fields are involved, massassignment should be restricted; when saving the associated model, beginTran should be combined

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

The method of creating custom operations in Yii is to define a common method starting with an action in the controller, optionally accept parameters; then process data, render views, or return JSON as needed; and finally ensure security through access control. The specific steps include: 1. Create a method prefixed with action; 2. Set the method to public; 3. Can receive URL parameters; 4. Process data such as querying the model, processing POST requests, redirecting, etc.; 5. Use AccessControl or manually checking permissions to restrict access. For example, actionProfile($id) can be accessed via /site/profile?id=123 and renders the user profile page. The best practice is
