Example #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.
