PHP监測memcache服务端的执行状况
代码例如以下，代码为memcache官方代码，引用在此。做一下简单的说明：
1、设置username和password
define('ADMIN_USERNAME','admin');
// Admin Username
define('ADMIN_PASSWORD','123456'); // Admin Password
2、配置server及其port，能够配置多台
$MEMCACHE_SERVERS[] = 'localhost:11211'; // add more as an array
$MEMCACHE_SERVERS[] = 'localhost:11212'; // add more as an array
