Use closures to be suitable for lightweight verification, such as preventing the user name "admin"; 2. Create Rule classes (such as ValidUsernameRule) to make complex logic clearer and maintainable; 3. Integrate multiple rules in form requests and centrally manage verification logic. At the same time, you can set prompts through custom messages methods or incoming error message arrays to improve flexibility and maintainability.

Use make:command to create a custom Artisan command and combine task scheduling to implement timing operations. 4. Use route:list, config:clear and other commands to debug and perform performance optimization to help troubleshoot configuration and caching problems.

The core methods for Laravel applications to implement multilingual support include: setting language files, dynamic language switching, translation URL routing, and managing translation keys in Blade templates. First, organize the strings of each language in the corresponding folders (such as en, es, fr) in the /resources/lang directory, and define the translation content by returning the associative array; 2. Translate the key value through the \_\_() helper function call, and use App::setLocale() to combine session or routing parameters to realize language switching; 3. For translation URLs, paths can be defined for different languages ​​through prefixed routing groups, or route alias in language files dynamically mapped; 4. Keep the translation keys concise and
