    <?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);

    Note: the result of the function is cached. The cached is not automatically refreshed.

    Call MemCache::getExtendedStats() to force a cache-update.

    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.
