Memcached::getStats() returns an array containing the state of all available memcache servers. See » memcache protocol specification for details on these statistics.
This function has no parameters.
Array of server statistics, one entry per server.
Example #1 Memcached::getStats() example
<?php
$m = new Memcached();
$m->addServer('localhost', 11211);
print_r($m->getStats());
?>
The above example will output something similar to:
Array
