Memcached::getStats — 獲取服務器池的統(tǒng)計信息
Memcached::getStats()返回一個包含所有可用memcache服務器狀態(tài)的數(shù)組. 返回的統(tǒng)計信息的詳細描述參見? memcache protocol。 （譯注：經(jīng)實驗，服務器池中有不可用服務器時，返回false）
此函數(shù)沒有參數(shù)。
服務器統(tǒng)計信息數(shù)組， 每個服務器一項。
示例 #1 Memcached::getStats() 示例
<?php
$m = new Memcached();
$m->addServer('localhost', 11211);
print_r($m->getStats());
?>
