Here's how you can make an udp broadcast, useful sometimes, and does seem hard to figure out hwo to do..



<?php

$sock = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);

socket_set_option($sock, SOL_SOCKET, SO_BROADCAST, 1);

socket_sendto($sock, $broadcast_string, strlen($broadcast_string), 0, '255.255.255.255', $port);

?>
