Developing Custom Middleware for Request Handling in Laravel
To create a custom middleware, use the Artisan command to generate the class file, 1. Write a logical processing request, 2. Register the middleware in Kernel.php, 3. Apply and pass parameters in the route. Middleware is used to filter HTTP requests. Laravel has a variety of built-in middleware, and users can also create custom logic based on their needs, such as verifying user roles. After creation, it needs to be registered as global or routing middleware, and can be called through the middleware method in the routing, supporting multiple middleware and parameter chains. Notes include: Ensure that $next($request) is called, pay attention to the execution order, keep the logic single, and sufficient testing.

How to perform database transactions in Laravel.
The key to handling database transactions in Laravel is to understand its mechanisms and usage scenarios, and implement them through DB facades or Eloquent. 1. Use the DB facade to control transactions: enable it through beginTransaction(), commit() commit(), rollback(), and handle exceptions in combination with try-catch; 2. Use transactions in Eloquent: wrap it in transactions through model operations to ensure consistency, but avoid nesting transactions in model events; 3. Simplified method: use the DB::transaction() method to automatically handle commits and rollbacks; precautions include ensuring that transactions are executed on the same connection, avoiding long-term running transactions, and not making them within transactions

How to use queues in Laravel?
Using queues in Laravel is to perform time-consuming tasks asynchronously, improve response speed and system performance. 1. Configure the queue driver: set QUEUE_CONNECTION through .env, such as redis or database, and create data tables or configure Redis parameters as needed; 2. Create queue tasks: Use the Artisan command to generate task classes, write execution logic in the handle() method, and use Queueabletrait and ShouldQueue interfaces; 3. Distribute queue tasks: Distribute tasks through the dispatch() method, specify the queue name and delay time; 4. Start queue worker: Run queue:work command

How to optimize Laravel performance?
The core of optimizing Laravel performance is to reduce resource consumption, improve response speed, rational use of cache and optimize database queries. 1. Optimize database query: Use with() to preload associated data to avoid executing queries in loops, use select() to specify fields, and enable query log debugging. 2. Reasonable use of cache: cache the entire API response or database results, select a suitable cache driver such as Redis, and set a reasonable cache time. 3. Optimize the code structure and request process: streamline middleware, delay loading service providers, reduce the number of event listeners executions, and avoid writing complex logic in the controller. 4. Use queues to process time-consuming tasks: push tasks to queues, use Redis as queue drivers, and configure multiple ws

What are accessors and mutators in Laravel?
In Laravel, accessors and modifiers are used to format or process model properties when they are acquired or set. 1. Accessors are used to modify the get value of attributes, such as formatting date or merge names, named as get{AttributeName}Attribute; 2. Modifiers are used to modify the stored value of attributes, such as hash password or formatting input, named as set{AttributeName}Attribute; 3. They are suitable for data formatting and simple conversion, but are not suitable for complex business logic; 4. When using it, they should follow naming specifications and pay attention to the consistency of data type processing and output.

Explain different Laravel Caching drivers.
Laravel supports a variety of cache drivers, suitable for different scenarios and performance requirements. 1.File driver is suitable for small applications, with simple configuration but low efficiency, and is not suitable for production environments; 2.Database driver realizes data persistence and sharing, with low performance, and is suitable for scenarios with low performance requirements; 3.Redis driver has high performance, supports distributed architecture and a complete expiration mechanism, and is the first choice for high performance; 4.Memcached driver is lightweight and efficient, suitable for page or object cache, but does not support complex data types; 5.Array driver is used for testing, and is only valid during the request life cycle and does not persist data. Just select the appropriate driver according to the project size and deployment situation.

How to use named routes in Laravel?
The core role of named routing in Laravel is to improve maintainability. It allows developers to generate URLs or redirects through names rather than hardcoded paths, and when the path changes, you only need to modify the name binding at the route definition. Use the name() method to name the route. It is recommended to use dot-delimited naming methods such as user.profile to enhance structural clarity. In a Blade template or controller, you can reference a named route through the route() function and pass in an array of parameters to generate a link or redirect it. Notes include avoiding name conflicts, matching parameters by name, and viewing all named routes through phpartisanroute:list.

What is Laravel Livewire?
The Livewire component is the basic unit for implementing dynamic front-end interactions in Laravel, which consists of PHP classes and Blade views. 1. PHP class processing logic, such as responding to events or updating data; 2. The Blade view is responsible for rendering HTML and binding interactive behavior.
