## What it is
The PSR-6 Caching Interface package from PHP-FIG, providing standard PHP interfaces for cache pools and cache items. It contains no implementation itself, only the contracts that caching libraries implement and applications consume.

## Use cases
- standardize cache usage across PHP libraries
- swap cache backends without changing application code
- write a PSR-6 compliant cache implementation
- type-hint against a common caching interface
- decouple framework code from specific cache vendors

## When to choose
- you are building a PHP library and want interoperable caching via a standard interface
- you need to implement or consume PSR-6 cache contracts
- you want vendor-agnostic caching in a framework-agnostic package

## When to avoid
- you need an actual working cache backend like Redis or Memcached
- your project uses PSR-16 simple cache instead of PSR-6
- you are not working in PHP

## Facets
- artifact type: library
- maturity: stable
- function: caching
- domain: developer-tools, web-development, backend
- platform: php
- tags: psr-6, psr, interfaces, standards, cache-interfaces
