Memcache::getServerStatus — Returns server status
Memcache::getServerStatus() returns a the servers online/offline status. You can also use memcache_get_server_status() function.
Hinweis:
This function has been added to Memcache version 2.1.0.
Point to the host where memcached is listening for connections.
Point to the port where memcached is listening for connections.
Returns a the servers status. 0 if server is failed, non-zero otherwise
Beispiel #1 Memcache::getServerStatus() example
<?php
/* OO API */
$memcache = new Memcache;
$memcache->addServer('memcache_host', 11211);
echo $memcache->getServerStatus('memcache_host', 11211);
/* procedural API */
$memcache = memcache_connect('memcache_host', 11211);
echo memcache_get_server_status($memcache, 'memcache_host', 11211);
?>
Beware... this method does not actually attempt to connect to the server and port you specify! It is not a health check to tell whether memcached is actually running or not!
It merely returns the server status from the pool, which defaults to TRUE when using addServer( ) with only required arguments.
Try it - stop your memcached and run the sample code above - it will output 1.
