How to handle form validation in Laravel?
There are four common ways to handle form verification in Laravel, which are suitable for different scenarios. 1. The validate() method in the controller is suitable for small and medium-sized projects, which can quickly verify fields and automatically redirect error information; 2. The form request class is suitable for complex logic or multiple reuse scenarios, making the controller more concise and easy to maintain; 3. Custom verification rules can be implemented through closures or Rule classes, and can customize error prompts to improve user experience; 4. The front-end displays error information through the Blade template, which can display field errors separately or summarize all errors. Choose the appropriate method according to the complexity of the project, and the verification rules should be as clear and complete as possible.

Explain Laravel Events and Listeners functionality.
Laravel's Events and Listeners are used to decouple application modules. Events indicate "what happened", such as user registration or order payment; listeners define "what to do", such as sending emails or logging. 1. The event class is stored in app/Events, carrying relevant information; 2. The listener is stored in app/Listeners, responding to events through handle methods; 3. Bind events and listeners in EventServiceProvider, or use automatic discovery mechanism; 4. Use event() or dispatch() to trigger events; 5. The listener can implement asynchronous processing, just add the ShouldQueue interface. This mechanism improves code clearance

How to define an optional route parameter in Laravel?
The methods for defining optional routing parameters in Laravel are as follows: 1. Add ? after the routing parameters to indicate optional, such as {name?}; 2. Set default values for parameters in the controller or closure to avoid errors; 3. Optional parameters must be at the end of the route to ensure correct resolution; 4. When using named routes, you can generate links by omitting parameters or leaving empty array items. Through these steps, optional parameters can be handled flexibly and avoid common problems such as parameter order errors or type prompt conflicts.

Understanding the Laravel Service Container and Binding?
Service containers are the core tool for Laravel to manage dependencies and perform dependency injection. They reduce coupling by automatically parsing dependencies and improve code testability and flexibility. 1. It is like a "factory", which automatically creates objects and manages its life cycle; 2. Binding is used to tell the container how to create class instances. Common methods include bind() (new every time), singleton() (singleton) and instance() (existing instances); 3. Common usage scenarios include interface and implementation binding, singleton binding shared resources, and conditional binding switching implementation; 4. It is not recommended to over-binding to keep the code concise and clear. Mastering service containers helps write more flexible and maintainable Laravel applications.
