psr11-usage

Use a PSR-11 container to retrieve the cache keys​

You can use a PSR-11 compatible to retrieve the cache keys. Once is defined, only the keys defined in the PSR-11 will be used to cache.

<?php
$fileCache = new \ByJG\Cache\Psr16\FileSystemCacheEngine()
$fileCache->withKeysFromContainer(new SomePsr11Implementation());

After the PSR-11 container is defined, when I run:

$value = $fileCache->get('my-key');

The key my-key will be retrieved from the PSR-11 container and the value retrieved will be used as the cache key. If it does not exist in the PSR-11 container, an exception will be thrown.
