- Here's a quick untested connect-disconnect done in PHP:

# port: port of server
|

function check_if_minetestserver_up($host, $port)

$timeout = array("sec" => 1, "usec" => 0);
|

socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO, $timeout);
|

$buf = "\x4f\x45\x74\x03\x00\x00\x00\x03\xff\xdc\x01";
|

socket_sendto($socket, $buf, strlen($buf), 0, $host, $port);
|

$buf = socket_read($socket, 1000);
|

if($buf != "")

{
|

# We got a reply! read the peer id from it.
|
||||
$peer_id = substr($buf, 9, 2);
|

|

# Disconnect

$buf = "\x4f\x45\x74\x03".$peer_id."\x00\x00\x02";
