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

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

Using different Guards in Laravel Authentication.
Laravel's Guard mechanism allows developers to define independent authentication processes for different user roles. By configuring multiple guards and providers in config/auth.php, for example, setting web and adminguard for ordinary users and administrators, and specifying the corresponding models and drivers. Use Auth::guard('guard-name') to specify the guard used for login and logout operations in the controller. The routing middleware can also bind a specific guard, such as auth:admin to protect the corresponding interface. Notes include ensuring that the model implements Authenticatable interface, session isolation and A

Writing Custom Validation Rules in Laravel.
In Laravel, custom validation rules can be implemented in three ways. 1. Use Rule::make to create closure verification rules, which are suitable for simple logic, such as checking whether the mailbox has been registered; 2. Create reusable rule classes, generate and implement validate methods through the Artisan command, which are suitable for large projects or multiple reused logic; 3. Centrally manage verification rules and prompt information in form requests to improve structural clarity and maintenance. In addition, error prompts can be customized by using $fail() or overridden messages() method. These methods effectively enhance the readability and maintainability of verification logic.

Understanding the `public` directory in Laravel.
The function of the public directory in Laravel is to store static resources that can be accessed directly by the browser. ① All publicly accessed pictures, CSS, and JS files should be placed in this directory. For example: /public/images/logo.png can be accessed through http://yourdomain.com/images/logo.png; ② Unlike the resources directory, the latter is used to store uncompiled front-end resources such as Blade templates, Sass files, etc.; ③ When configuring the web server, you need to point the root directory to public, such as Apache sets DocumentRoot to your-project/public; ④ Common

Setting up and using Cron Jobs for Laravel Scheduler.
CronJob is an operating system-level timing task mechanism, which LaravelScheduler relies on triggering execution. To set CronJob, you need to edit the crontab file and add a command like *php/path/to/artisanschedule:run>>/dev/null2>&1. Defining tasks in Laravel requires the frequency setting in the schedule method of app/Console/Kernel.php, such as command()->daily(), and the conflict can be prevented by -> without Overlapping().

Explain Laravel's IoC Container binding methods (`bind`, `singleton`, `instance`).
The difference between the three binding methods of bind, singleton and instance in Laravel's IoC container is that the instance creation and reuse methods are different. 1.bind creates a new instance every time it resolves, suitable for stateless services or short-term tasks; 2. singleton creates an instance only once during the entire request life cycle, suitable for global shared services such as database connections; 3. Instance directly binds existing instances, suitable for testing environments or manually controlling instance creation. These three methods correspond to different usage scenarios, and understanding their differences will help better manage dependencies and service life cycles.

How does Soft Deletes work in Laravel Eloquent?
Soft deletion in LaravelEloquent marks the record as deleted rather than actually removed by adding the deleted_at column. 1. Use the SoftDeletes feature and introduce it in the model; 2. The database table must contain the deleted_at column, which is usually added by the migration file using $table->softDeletes(); 3. Only the deleted_at timestamp is set when calling the delete() method; 4. The default query does not contain soft delete records, but can be obtained through withTrashed() or onlyTrashed(); 5. Use forceDelete() to completely delete soft delete records; 6. Use rest

Understanding the differences between Laravel Breeze and Jetstream.
The main difference between LaravelBreeze and Jetstream is positioning and functionality. 1. In terms of core positioning, Breeze is a lightweight certified scaffolding that is suitable for small projects or customized front-end needs; Jetstream provides a complete user system, including team management, personal information settings, API support and two-factor verification, which is suitable for medium and large applications. 2. In terms of front-end technology stack, Breeze uses Blade Tailwind by default, which prefers traditional server-side rendering; Jetstream supports Livewire or Inertia.js (combined with Vue/React), which is more suitable for modern SPA architectures. 3. In terms of installation and customization, Breeze is simpler and easier to use
