Understanding the Request Lifecycle in Laravel.
The Laravel request life cycle starts from public/index.php, loads the framework and hands it over to the HTTP kernel for processing; the kernel executes global, grouping and routing middleware, and calls next() in order to advance the process; then the framework matches the route and calls the corresponding controller method, injects dependencies through the service container; finally returns the response and executes the end processing, including closing the connection and saving the Session.

How to test a console command in Laravel?
Use artisan() or Artisan::call() to run console commands in Laravel tests; 2. Verify that the command is successfully executed by assertExitCode(0); 3. When passing parameters, you can pass in arrays to specify parameters and options in artisan(); 4. For interactive commands, use expectsQuestion() to simulate user input; 5. Use expectsOutput() and doesn'tExpectOutput() to assert whether the output content contains or does not contain specific text; 6. By combining these methods, you can test the behavior, input and output of the command to ensure that it works as expected.

How to schedule tasks using the Laravel scheduler?
Laravel's scheduled tasks simplify task management with built-in scheduler. First, define tasks in the schedule() method of the App\Console\Kernel class, such as running Artisan commands, executing closures or calling scripts; second, use frequency shortcut methods such as ->daily(), ->hourly(), etc. to set the execution cycle; then you can control the task running conditions through environment filtering ->environments(), condition judgment ->when(), etc.; finally, manually execute the phpartisanschedule:run test task, and combine logs and monitoring tools to ensure the normal operation of the task.

Using the `with()` method for eager loading in Laravel.
Using Eloquent's with() method can effectively avoid N 1 query problems. Its core function is to preload the specified relationship and reduce the number of queries when subsequent access to the associated data. For example, iterating through $user->posts when with() is not used will trigger multiple queries, while all associated data will be loaded at once via User::with('posts')->get(). Common usage scenarios include displaying blog posts and their authors, user orders and details, categories and subcategories, etc. For nested or multiple relationships, multi-level relationships can be loaded through point syntax such as roles.permissions or array parameters. Note when using: only load relationships when needed,

Securing APIs using Laravel Passport or Sanctum.
LaravelPassport is suitable for applications that require issuing access tokens to third-party clients and supports OAuth2 standard process; Sanctum is suitable for protecting first-party API calls, making it lighter and simpler. 1. If third-party access control is required, use Passport: install, migrate, configure the User model and AuthServiceProvider. 2. If it is an internal SPA or mobile interface, select Sanctum: install, publish configuration, and add middleware. Both can manage token scope and expiration time, but Passport has built-in scope control, while Sanctum needs to be implemented by itself. All routes are via auth:sanctum or auth:passp

Using Laravel's `dd()` and `dump()` for debugging.
dd() and dump() in Laravel are commonly used debugging tools. dd() is used to print variables and terminate script execution. It is suitable for checking the data status in a specific location, such as viewing the return value of the method or the request parameters are correct; dump() only prints the variable content without interrupting the program flow, which is suitable for viewing multiple variable values in succession; both support multi-parameter printing, which can be used to debug collections and chain operation results, and the output information will be formatted and highlighted by type color, which is easy to read, but it should be noted that they are only used in the development stage and should be removed before going online to avoid leakage of sensitive information.

How to clear cache in Laravel?
Run phpartisancache:clear to clear the application cache; 2. Run phpartisanroute:clear to clear the route cache; 3. Run phpartisanconfig:clear to clear the configuration cache; 4. Run phpartisanview:clear to clear the view cache; 5. Optionally execute composerdump-autoload to regenerate the class map; in development, these commands can be executed in turn to completely clear the cache. After the production environment is cleared, config:cache and route:cache should be re-executeed to improve performance. The problems are usually made by cache:clear and view:clear

How does Laravel's service container use reflection for auto-wiring?
Laravel's container uses the PHP reflection API to automatically parse class dependencies to achieve automatic assembly; 1. When requesting to parse a class, if the constructor parameter has a type prompt and can be parsed, it can be instantiated without explicit binding; 2. The container obtains constructor parameters through ReflectionClass, uses ReflectionParameter to read the type prompt and recursively parse each dependency; 3. Reliability is recursively parsed according to the graph, such as the OrderController relies on the OrderService, which relies on the OrderRepository, and finally builds layer by layer from the bottom layer; 4. If the parameter has no type prompt, is a basic type or has no binding to the interface, an exception is thrown unless provided

Working with Laravel Collection methods (map, filter, reduce).
The map, filter and reduce methods in the Laravel collection can efficiently process data. 1. Map is used to convert each element in the collection, suitable for formatting or reconstructing data; 2. Filter is used to filter elements that meet the conditions, suitable for filtering invalid or specific conditions data; 3. Reduce is used to summarize data, such as calculating the sum or counting the number of classifications. These methods make the code more concise and easy to maintain, and are suitable for handling small and medium-sized datasets.

How to create a one-to-many relationship in Laravel?
The key to creating a one-to-many relationship in Laravel is to correctly set up the model and database structure. First, define the database table structure, the users table contains id, and the posts table contains the user_id foreign key pointing to users.id; secondly, use hasMany to define one-to-many relationships in the User model, and use belongsTo to define the reverse relationship in the Post model; finally query the data through $user->posts or $post->user, and use with() to preload to optimize performance; at the same time, pay attention to the consistent type of foreign key field, correct naming and correct reference to the model namespace to ensure that the relationship works normally.

The MVC Pattern in Laravel.
Laravel's MVC architecture improves development efficiency and collaboration convenience by separating code into three parts: Model, View and Controller. 1. The Controller receives the request and returns the response, defined in the app/Http/Controllers directory, can be generated using the Artisan command, and automatically generates the CRUD method with the --resource parameter; 2. The Model uses EloquentORM to interact with the database, corresponds to the data table by default, and supports definition of association relationships, which are often used to query and save data; 3. The View uses the Blade template engine to organize the front-end page, located in the resources/views directory, and supports inheritance
