What is the cache system in Laravel?
คำตอบ
Laravel cache allows temporarily storing expensive-to-compute data to improve application performance. Laravel provides a unified API for different cache backends (Redis, Memcached, file, database, array). Caching reduces repetitive database queries and speeds up response times by keeping results in memory or on disk.
2What cache drivers are supported by Laravel?
What cache drivers are supported by Laravel?
คำตอบ
Laravel supports multiple cache drivers: file (disk storage), database (dedicated table), Redis (fast in-memory), Memcached (distributed in-memory), DynamoDB (cloud), array (in-memory, tests only), and null (no caching). Each driver has specific use cases: Redis for performance, file for simplicity, database to avoid external dependencies, array for testing.

Using Cache::put('key', 'value', 60) stores a value with a 60-second lifetime. The first parameter is the unique key, the second is the value (can be array, object, string), the third is duration in seconds. After expiration, the key is automatically removed from cache.
