Applying Global or Group Middleware in Laravel
In Laravel, duplicate code can be reduced through global middleware and middleware groups. Global middleware is suitable for all requests, such as setting time zones and loading language packs. The registration method is to add class names to the $middleware array of app/Http/Kernel.php, but time-consuming operations should be avoided; middleware groups are used to apply multiple middleware to a set of routes on demand, such as web and API groups, and can be customized and applied to routes, such as authentication and permission judgment middleware to form an admin group, and applied through Route::middleware('admin'); global middleware is selected for system-level operations, and middleware groups are used for business division, thereby improving project structure clarity and maintainability.

Handling File Uploads and Storage in Laravel?
Implementing file upload and storage in Laravel requires configuring the file system, processing upload logic, controlling access rights and regular maintenance. 1. Configure filesystems.php to select local, public or S3 disks; 2. Use request()->file() to obtain files and call store() or storeAs() to store them in the specified directory; 3. Generate access links through Storage::url() or custom controllers to restrict access; 4. Clean redundant files regularly, delete files simultaneously when deleting database records.

Mocking Dependencies and Facades in Laravel Tests
Mocking dependencies and facades can improve Laravel testing efficiency and reduce side effects, because real execution of external resources will cause the test to be slow, unstable and difficult to control the state; correct mockfacades should use Facade::shouldReceive() instead of ordinary instance mock; combined with Mockery can make the syntax more concise and intuitive, but you need to pay attention to cleaning up the state, avoiding excessive mocking and parameter matching problems.

Comparing and Choosing Caching Drivers for Laravel
The selection of Laravel cache drivers needs to be determined based on the project size and deployment environment. 1. File cache is suitable for local development or small projects. Its advantage is that it does not require external services. The disadvantage is that it is poor concurrency and is not suitable for multiple servers. 2. Database cache is suitable for scenarios with existing database connections. The advantage is that data can be persisted, and the disadvantage is that it affects database performance. 3. Redis is suitable for high-concurrency and distributed projects. It has good performance and supports clusters, but requires additional installation of services. 4. Memcached is suitable for key-value pair cache, which is fast but has limited functions and does not support persistence. Drivers can be switched according to the environment, such as local file and redis in production environment.

Select a storage driver according to project needs, such as the local disk is suitable for small and medium-sized projects, and S3 is suitable for production environments; 3. Use a unique naming strategy to improve security and avoid path crossing and script execution risks; 4. After uploading, save the relative path to the database, and use Storage::url() to generate signature links to ensure that path information is recorded one by one when multiple files are uploaded.

One-to-many relationships are defined by the hasMany method, and the primary key id is matched to the foreign key user_id by default, and foreign keys can also be specified manually; 3. Many-to-many relationships require intermediate tables and are defined by belongsToMany, and the intermediate table names and additional fields can be loaded with Pivot; 4.

How do I create custom actions in a Yii controller?
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.

Securing Laravel APIs with Sanctum or Passport Authentication
LaravelSanctum and LaravelPassport are two tools for API authentication, suitable for different scenarios. 1.Sanctum is simpler and lightweight, suitable for SPAs, mobile applications and basic token authentication; 2. Passport is a complete OAuth2 server, supporting third-party access tokens, token revocation and fine scope control. If you need OAuth2 function, use Passport, otherwise Sanctum is more suitable. The settings process of the two are different: Sanctum needs to install, publish configuration, run migration, update user model and add middleware, and generate tokens through the createToken method; Passport needs to install, run migration,

Defining and using local and global scopes in Laravel Eloquent
In LaravelEloquent, the global scope is automatically applied to each query, suitable for scenarios such as filtering inactive users; the local scope needs to be called manually, suitable for scenarios such as displaying published articles only in a specific context. 1. Global scope is implemented by implementing the Scope interface and registering it in the model, such as adding where('active',true) condition. 2. Local scope is a method in the model, starting with scope and can take parameters, such as scopeVerified() or scopeOfType(). 3. When using global scope, its impact on all queries should be considered. If necessary, you can exclude it by without GlobalScopes(). 4. Choose to do it
