Laravel's configuration cache improves performance by merging all configuration files into a single cache file. Enabling configuration cache in a production environment can reduce I/O operations and file parsing on each request, thereby speeding up configuration loading; 1. It should be enabled when the application is deployed, the configuration is stable and no frequent changes are required; 2. After enabling, modify the configuration, you need to re-run phpartisanconfig:cache to take effect; 3. Avoid using dynamic logic or closures that depend on runtime conditions in the configuration file; 4. When troubleshooting problems, you should first clear the cache, check the .env variables and re-cache.

Create referrals table to record recommendation relationships, including referrals, referrals, recommendation codes and usage time; 2. Define belongsToMany and hasMany relationships in the User model to manage recommendation data; 3. Generate a unique recommendation code when registering (can be implemented through model events); 4. Capture the recommendation code by querying parameters during registration, establish a recommendation relationship after verification and prevent self-recommendation; 5. Trigger the reward mechanism when recommended users complete the specified behavior (subscription order); 6. Generate shareable recommendation links, and use Laravel signature URLs to enhance security; 7. Display recommendation statistics on the dashboard, such as the total number of recommendations and converted numbers; it is necessary to ensure database constraints, sessions or cookies are persisted,

Use the composerremove command to uninstall packages in PHP projects. This command removes the specified package from the composer.json's require or require-dev and automatically adjusts the dependencies. 1. Execute composerremovevevendor/package to remove from require; 2. Use the --dev parameter to remove from require-dev; 3. Composer will automatically update the dependencies and rebuild the automatic loader; 4. You can run composerinstall and check the vendor/directory to ensure thorough cleaning; 5. Finally submit version control changes to save the modification.

Create a seeder file: Use phpartisanmake:seederUserSeeder to generate the seeder class, and insert data through the model factory or database query in the run method; 2. Call other seeder in DatabaseSeeder: register UserSeeder, PostSeeder, etc. in order through $this->call() to ensure the dependency is correct; 3. Run seeder: execute phpartisandb:seed to run all registered seeders, or use phpartisanmigrate:fresh--seed to reset and refill the data; 4

Using events and listeners in Laravel is an effective way to decouple main logic. 1. Create events and listeners can be generated and bound to EventServiceProvider through the Artisan command or enable the automatic discovery mechanism. 2. In actual use, it is necessary to note that an event can correspond to multiple listeners, queue failure retry policy, keep the listener lightweight, and register event subscribers. 3. During testing and debugging, you should confirm the event triggering, listener binding, and queue drive status, and set QUEUE_CONNECTION=sync to perform synchronously to facilitate troubleshooting. 4. Advanced tips include dynamically controlling the execution or registration of the listener according to conditions, but it is recommended to advanced users. Mastering these key points can help improve code control
