When using socket_set_timeout($MyVar, 2); I get an error message returned stating: "socket_set_timeout() is not supported in this PHP build".  I went to look at the help at PHP.net for socket_set_timeout and it's in versions >= 4.  I'm running 4.1.2 on Windows 2000.  I read that it's a replacement for set_socket_timeout().  When using set_socket_timeout() I get a fatal error.  Here's the main part of the function that I'm using:

function query_tribes2($ip, $port) {
	$tqSocket = fsockopen("udp://$ip", $port);
	$tqSocket2 = fsockopen("udp://$ip", $port);

	if ($tqSocket && $tqSocket2) {
		$binary = pack("CCL", 14, 2, 1234);
		$binary2 = pack("CCL", 18, 2, 1234);
	
		socket_set_blocking($tqSocket, 0);
		socket_set_blocking($tqSocket2, 0);
		socket_set_timeout($tqSocket, 2);
		socket_set_timeout($tqSocket2, 2);
