我有以下代码:

$cluster['local'] = array('host' => '192.168.1.1', 'port' => '11211', 'weight' => 50);
$cluster['local2'] = array('host' => '192.168.1.2', 'port' => '11211', 'weight' => 50);

$this->memcache = new Memcache;

foreach ($this->cluster() as $cluster) {
    $this->memcache->addServer($cluster['host'], $cluster['port'], $this->persistent, $cluster['weight'], 10, 10, TRUE , 'failure' );
}

我想创建一个函数来检查我的memcache池中的任何服务器是否可用.怎么可以这样做？
