README
PHP library that allows to search keys in memcache. It uses lru_crawler

Why it's better then other solution?
- Standart

which is based onmemcached_dump
function which is not guarentee to dump all keys. Also it reported that staring memcache 1.4.23 this function does not work. - Standart
Memcache
extension does not have such functionallity and have different solutions based onstats cachedump
which have memcache server performance impact and once again not guarentee to dump all keys.
