How to extend Laravel's core components (e.g., custom guard).
To create and register a custom Guard in Laravel, 1. Create a class that implements the Guard interface or inherits GuardHelpers; 2. Register the Guard with Auth::extend() in the service provider; 3. Add a new Guard configuration item in the auth.php configuration file; 4. If you need special user acquisition logic, you also need to customize and register the UserProvider. After the above steps are completed, you can call the custom authentication logic by specifying the Guard name.

Generating URLs for Named Routes in Laravel.
The most common way to generate a named route in Laravel is to use the route() helper function, which automatically matches the path based on the route name and handles parameter binding. 1. Pass the route name and parameters in the controller or view, such as route('user.profile',['id'=>1]); 2. When multiple parameters, you only need to pass the array, and the order does not affect the matching, such as route('user.post.show',['id'=>1,'postId'=>10]); 3. Links can be directly embedded in the Blade template, such as viewing information; 4. When optional parameters are not provided, they are not displayed, such as route('user.post',

Implementing HTTP/2 Server Push with Laravel.
To implement HTTP/2serverpush in Laravel, you must first configure the server to support HTTP/2 and enable SSL; then trigger push through the Link field in the response header; you can also dynamically control the push content in combination with the Blade template; but you need to pay attention to issues such as browser compatibility, resource size and CDN impact. The specific steps are: 1. Ensure that Nginx or Apache enables HTTP/2 and SSL/TLS; 2. Add Link headers to the response for resource preloading; 3. Pass the resource path through the controller and generate Link headers in the middleware; 4. Avoid repeated pushes, excessive resources, and misuse of the development environment.

Generating and using database factories in Laravel.
Database Factory is a tool in Laravel for generating model fake data. It quickly creates the data required for testing or development by defining field rules. For example, after using phpartisanmake:factory to generate factory files, sets the generation logic of fields such as name and email in the definition() method, and creates records through User::factory()->create(); 1. Supports batch generation of data, such as User::factory(10)->create(); 2. Use make() to generate uninvented data arrays; 3. Allows temporary overwriting of field values; 4. Supports association relationships, such as automatic creation

Using Artisan tinker for debugging in Laravel.
ArtisanTinker is a powerful debugging tool in Laravel. It provides an interactive shell environment that can directly interact with applications to facilitate rapid problem location. 1. It can be used to verify model and database queries, test whether the data acquisition is correct by executing the Eloquent statement, and use toSql() to view the generated SQL; 2. It can test the service class or business logic, directly call the service class method and handle dependency injection; 3. It supports debugging task queues and event broadcasts, manually trigger tasks or events to observe the execution effect, and can troubleshoot problems such as queue failure and event failure.

Explain the concept of Service Container 'binding' in Laravel.
In Laravel, "binding" refers to the parsing method of registering classes, interfaces or services through the service container to achieve automatic dependency injection. The essence of binding is to define how to create or obtain an instance of a dependency, rather than simple storage. Common types include simple binding, interface-to-implementation binding, and singleton binding. Binding should be performed in the service provider's register() method, which is suitable for situations where switching implementations, complex construction parameters, or third-party class injection, but problems such as excessive use or uncleared binding cache should be avoided.

Explain Laravel Blade Templating Engine.
Blade is a template engine that comes with the Laravel framework, and its core lies in "inheritance" and "placeholding". 1.Blade defines placeholders through @yield, and subpages use @extends and @section to replace content blocks to achieve a unified page style. 2.Blade supports variable output ({{$variable}}), non-escaped output ({!!$html!!}) and control structure (@if, @foreach, etc.). 3.Blade allows the introduction of subviews (@include) and supports multi-layer template inheritance. 4. Starting from Laravel7, Blade introduces components and slot mechanisms, similar to the front-end framework, by using components and inserting custom content. 5

Difference between Gates and Policies in Laravel Authorization.
In Laravel, gates are used for model-independent global permission checks, while policies are used for model-independent structured authorization logic. 1.Gates is a closure-based check, suitable for judgments such as "whether the user can access the dashboard"; 2.Policies are bound to the model and centrally manage the authorization logic, such as defining whether the user can update a certain article; 3.Gates are simple and lightweight, suitable for one-time inspection, and Policies are easier to test and expand; 4. Laravel will automatically match the policy method according to the model, without manual association. Both can be used in the same application.

Implementing Custom Authentication Logic in Laravel.
To go beyond Laravel's built-in authentication system, it can be implemented through custom authentication logic, such as handling unique login processes, third-party integrations, or user-specific authentication rules. 1. You can create a custom user provider, obtain and verify the user from non-default data sources by implementing the UserProvider interface and defining methods such as retrieveById, and register the provider in config/auth.php. 2. Custom login logic can be written in the controller, such as adding additional checks after calling Auth::attempt(), or using Auth::login() to manually authenticate users. 3. You can use middleware to perform additional verification, such as checking whether the user is "active"

Handling Failed Queue Jobs and Retries in Laravel.
To handle failed queue tasks and retry mechanisms in Laravel, you must first understand how it works and configure it reasonably. 1. Failed tasks will be automatically recorded in the failed_jobs table, provided that phpartisanqueue:failed-table has been run and the migration has been completed; common causes of failure include database errors, API call failures, serialization exceptions and uncaught exceptions. It is recommended to combine logs or third-party tools such as Sentry for problem location. 2. The global maximum number of retry times can be set through the command line parameter --tries=3, or the $tries attribute can be defined in the task class for fine-grained control; at the same time, use --timeout=30 to avoid long-term occupation of wor

What are some useful Laravel Artisan commands?
LaravelArtisan provides a variety of commands to improve development efficiency. 1. Quickly generate code templates: use make:model, make:controller, make:migration to create models, controllers and migration files, and support batch generation of parameters such as -mfcs; 2. Manage database migration: migrate runs migration, migrate:rollback rollback, migrate:fresh resets the database; 3. Clear cache optimization performance: config:clear, route:clear, and view:clear clear configuration, routing, and view caches respectively, optimize:clear clears all in one click

Understanding Laravel's project directory structure.
Laravel's directory structure follows the principle of conventions over configuration, and understands that it can speed up development efficiency and facilitate team collaboration. 1.app/ is the core code directory, including Controllers processing requests, Models defining data model (the namespace needs to be modified and references are updated in auth.php), Providers registering services; 2.routes/manage routing, web.php is used for web page requests, api.php is used for stateless interfaces, and can customize module routing files and introduce them through RouteServiceProvider; 3.database/ contains migrations database migrations, seeds initialization data, factori
