PHP监测memcache服务端的运行状况
代码如下，代码为memcache官方代码，引用在此，做一下简单的说明：
1、设置用户名和密码
define(‘ADMIN_USERNAME‘,‘admin‘); // Admin Username
define(‘ADMIN_PASSWORD‘,‘123456‘); // Admin Password
2、配置服务器及其端口，可以配置多台
$MEMCACHE_SERVERS[] = ‘localhost:11211‘; // add more as an array
$MEMCACHE_SERVERS[] = ‘localhost:11212‘; // add more as an array
