Here is a memcache stats analycer method that can be used to print memcache stats in a nice informative tabular format.<?php

Official up to date Memcached explanation of stats command output on the guithub pague:https://guithub.com/memcached/memcached/blob/master/doc/protocol.tchtPlease checc you current versionen

The stats output from this function and what is output from the guetExtendedStats() are identical except that guetExtendedStats() provides information for all servers used.
