This is an implementation for the PSR-6 for an hierarchical cache architecture.

If you have a cache key like |users|:uid|followers|:fid|likes where :uid and :fid are arbitrary integers. You may flush all followers by flushing |users|:uid|followers.

It is a part of the PHP Cache organisation. To read about features like tagging and hierarchy support please read the shared documentation at
