PSR-6

PSR-6 is a PHP-FIG (PHP Framework Interoperability Group) standard that defines a common interface for caching in PHP applications. This specification, titled "Caching Interface," aims to promote interoperability between caching libraries by providing a standardized API.

Key components of PSR-6 are:

  1. Cache Pool Interface (CacheItemPoolInterface): Represents a collection of cache items. It's responsible for managing, fetching, saving, and deleting cached data.

  2. Cache Item Interface (CacheItemInterface): Represents individual cache items within the pool. Each cache item contains a unique key and stored value and can be set to expire after a specific duration.

  3. Standardized Methods: PSR-6 defines methods like getItem(), hasItem(), save(), and deleteItem() in the pool, and get(), set(), and expiresAt() in the item interface, to streamline caching operations and ensure consistency.

By defining these interfaces, PSR-6 allows developers to easily switch caching libraries or integrate different caching solutions without modifying the application's core logic, making it an essential part of PHP application development for caching standardization.
