<?php
    $sh = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
    if (socket_bind($sh, '127.0.0.1', 4242)) {
        echo "Socket bound correctly";
    }
    $buf = 'Test Message';
    $len = strlen($buf);
    if (socket_sendto($sh, $buf, $len, 0x100, '192.168.0.2', 4242) !== false) {

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



$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);
