How to delete cache in laravel

When developing projects using Laravel, we usually use caching to improve application performance and loading speed. Caching can store common data and operations in memory, thereby reducing processing complexity and response time. However, when we need to update the cache, we need to know how to delete it.

php artisan cache:clear

Delete caches with specified tags

In Laravel, we can also add tags to cache items to organize related items. To delete caches with specified tags, use the cache:tags command. For example, if we want to delete cached items with the tag users, we can run the following command:

php artisan cache:tags users clear

This command will delete cached items with the specified tag. If no tag is specified, all cache entries will be deleted.

Delete specific cache items

To delete specific cache items, you can use the forget method. This method accepts one parameter, which is the cache key to delete. For example, we have a cache item with the cache key users, which can be deleted using the following code:

Cache::forget('users');

If you want to delete multiple cache items, you can use forget The second parameter of the method is an array containing all cache keys to be deleted. For example:

Cache::forget(['users', 'orders', 'products']);

Delete all cache items

If you want to delete all cache items, you can use the flush method. This method will remove all items from the cache.

Cache::flush();
