It is a part of the PHP Cache organisation. To read about features like tagging and hierarchy support please read the shared documentation at [www.php-cache.com](http://www.php-cache.com). ### Install [](#install) ``` composer require cache/chain-adapter ``` ### Use [](#use) You do not need to do any configuration to use the `CachePoolChain`. ``` $redisPool = new RedisCachePool($redisClient); $apcPool = new ApcCachePool(); $pool = new CachePoolChain([$apcPool, $redisPool]); ``` ### Contribute [](#contribute) Contributions are very welcome! Send a pull request to the [main repository](https://github.com/php-cache/cache) or report any issues you find on the [issue tracker](http://issues.php-cache.com). ### Health Score 42 — FairBetter than 90% of packages Maintenance18 Infrequent updates — may be unmaintained Popularity45 Moderate usage in the ecosystem Community25 Small or concentrated contributor base Maturity69 Established project with proven stability Bus Factor1 Top contributor holds 62% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
