Explain Laravel Eloquent Scopes.
Laravel's EloquentScopes is a tool that encapsulates common query logic, divided into local scope and global scope. 1. The local scope is defined with a method starting with scope and needs to be called explicitly, such as Post::published(); 2. The global scope is automatically applied to all queries, often used for soft deletion or multi-tenant systems, and the Scope interface needs to be implemented and registered in the model; 3. The scope can be equipped with parameters, such as filtering articles by year or month, and corresponding parameters are passed in when calling; 4. Pay attention to naming specifications, chain calls, temporary disabling and combination expansion when using to improve code clarity and reusability.

How to mock facades in Laravel tests?
Use Facade::shouldReceive() to accurately control the call, parameters and return values of the facade method, which is suitable for scenarios that require fine-grained simulation; 2. For common facades such as Mail and Notification, built-in fake methods such as Mail::fake() should be used first, which is more concise and less prone to errors; 3. When simulating chain calls, you must fully describe the call chain such as Mail::to()->send(); 4. Only specific methods can be simulated through partialmock and retain other real behaviors; 5. Avoid setting only mocks required for individual tests in setUp() to prevent pollution between tests; 6. Use Mail::preventSt

How do I validate form data in Yii?
The core method of validating form data in Yii is to define verification rules through the model and display errors using ActiveForm. 1. Define field rules in the rules() method of the model, such as required items, format restrictions and length constraints; 2. Automatically display verification error information when building forms using ActiveForm; 3. You can manually traverse getErrors() to get all errors; 4. You can add custom verification methods or anonymous functions to judge for complex logic. The entire process is automatically processed by the framework, which is both flexible and efficient.

What is dependency injection in Laravel?
Dependency injection (DI) improves code flexibility and testability by automatically parsing class dependencies in Laravel. Laravel uses service containers to automatically resolve dependencies for type prompts. For example, when declaring UserService or UserRepository types in controller constructors or methods, the framework will automatically instantiate and pass in the corresponding object. Binding interfaces to specific implementations (such as through the service provider bind method) allows flexible switching of implementation classes, suitable for different environments or test scenarios. The main advantages of using DI include loose coupling, easy testing and neat code; suitable for classes with external dependencies, maintenance or replacement implementations, avoiding simple or internal logical dependencies.
