Add a distributed number of memcached servers

If you have more than one memcached server side, it is best to use memcache::addserver () to connect the service Frontend. instead of Memcache::connect () to connect to the memcached server, the PHP client uses the server pool to assign keys to different servers based on the algorithm.

1. BOOLMemcache::Addserver(string$host[,int$port=11211[,BOOL$persistent[,int$weight[,int$timeout[,int$retry _interval[,BOOL$status[,Callback $failure _callback[,int$timeoutms]]]]]]]])

The first parameter $host: Represents the address of the server, the second parameter $port: Represents a port, the third parameter $persistent: Indicates whether it is a persistent connection, the default is true, and the fourth parameter $weight: Represents the weight of this server on all servers The fifth parameter $timeout: Indicates the duration of the connection; the sixth parameter $Retry_interval: Indicates the interval between connection retries, the default is 15, and a setting of 1 means no retries;The seventh parameter $status: used to control the server's online status;
Eighth parameter $failure_callback: allows you to set a callback function to handle error messages.Get status information for the server:1.

1. array Memcache::getStats ([string $type [,int $slabid [,int $limit =100]]]) //获取当前服务器的运行状态

2. <?php
4. $memcache_obj =newMemcache;
6. $memcache_obj->addServer(‘127.0.0.1‘,11211);
8. var_dump($memcache_obj->getStats());
10. ?>

2.

1. array Memcache::getExtendedStats ([string $type [,int $slabid [,int $limit =100]]]) //获取所有服务器扩展状态信息

2. <?php
4. $memcache_obj =newMemcache;
6. //返回一个二维关联数组的服务器统计信息或者在失败时返回 FALSE
8. $memcache_obj -> addServer (‘memcache_host‘,11211);
10. $memcache_obj -> addServer (‘failed_host‘,11211);
14. $stats = $memcache_obj -> getExtendedStats ();
16. print_r ( $stats );
18. ?>

3.

1. intMemcache::getServerStatus (string $host [,int $port =11211])//输入主机和端口信息来获取相应的服务器状态信息

2. <?php
6. /* OO API */
8. $memcache =newMemcache;
10. $memcache -> addServer (‘memcache_host‘,11211);
12. echo $memcache -> getServerStatus (‘memcache_host‘,11211);
16. /* procedural API */
18. $memcache = memcache_connect (‘memcache_host‘,11211);
20. echo memcache_get_server_status ( $memcache ,‘memcache_host‘,11211);
24. ?>
