Laravel's Artisan command line tool improves development efficiency through code generation, database management, custom commands and debug optimization. 1. Use the make:* series commands to quickly generate controller, model, middleware and other files, and support resource controllers and single action controllers. 2. Manage database structure and data through commands such as migrate, db:seed, etc., and support migration rollback and reset. 3. 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.

In Laravel development, Artisan command line tools are the key assistants for improving efficiency. It not only provides commands to quickly generate code, but also helps you manage system functions such as databases, queues, and caches. Mastering some commonly used Artisan commands and techniques can significantly improve development efficiency.

1. Quickly generate code structure: make:* series commands

Laravel's make:* command allows you to generate common files such as controllers, models, middleware, and service classes in just a few seconds. for example:

• php artisan make:controller UserController
• php artisan make:model Post -mf (create migration, factory and seeder at the same time)
• php artisan make:middleware TrimInput

These commands save the hassle of manually creating files and directories, and also ensure consistency of naming specifications.

Tips:

• Add -r or --resource to generate resource controllers directly.
• Use --invokable to create a controller that only contains the __invoke method, suitable for single action routing.

2. Database operation tools: migration and filling

Artisan is very powerful in database operations. Several key commands are as follows:

• php artisan migrate : run all unexecuted migrations
• php artisan migrate:rollback : rollback the last migration
• php artisan db:seed : Run the data filler to fill the test data
• php artisan make:migration create_users_table : create a new migration file

You can use these commands in combination to manage database structure and content, for example:

 php artisan migrate:fresh --seed

This command empties the database and reruns all migrations and seeds, making it ideal for local environment resets.

3. Custom Artisan command: encapsulate common logic

If you have some business logic that you often need to run, consider encapsulating it with Artisan custom commands. Create one with the following command:

 php artisan make:command SendDailyEmails

Then edit the generated class and write your logic in handle() method. After that, you can pass:

 php artisan send:daily-emails

Come to run. Combined with Cron Job or Laravel task scheduling, this type of command is particularly suitable for timed cleaning, sending notifications, etc.

4. Debugging and Optimization Command: Check the project status

Sometimes you need to quickly understand the structure or performance status of your project, Artisan provides some practical debugging commands:

• php artisan route:list : View all registered routes
• php artisan config:clear / cache:clear : Clear configuration or view cache
• php artisan optimize : optimize automatic loading (although Composer is now very efficient)

These commands are very useful when deploying or debugging, especially when you encounter a problem like "why the configuration is not effective", running the command to clear the cache first can usually solve the problem.

Basically that's it. Proficient in using Artisan not only saves a lot of repetitive labor, but also helps you better understand Laravel's internal mechanisms.
