Notes (SERVER)

• Install dependencies - composer install
• Create src/socket.php

<?php

namespace App;

use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;

class Socket implements MessageComponentInterface {

    public function __construct()
    {
        $this->clients = new \SplObjectStorage;
    }

    public function onOpen(ConnectionInterface $conn) 
    {
        ....
    }

    public function onMessage(ConnectionInterface $from, $msg) 
    {
        ....
    }

    public function onClose(ConnectionInterface $conn) 
    {
        ....
    }

    public function onError(ConnectionInterface $conn, \Exception $e) 
    {
        ....
    }
}

• Create run php bash script - Executable in CLI

#!/usr/bin/env php

<?php

use Ratchet\Server\IoServer;
use Ratchet\Http\HttpServer;
use Ratchet\WebSocket\WsServer;
use App\Socket;

require dirname( __FILE__ ) . '/vendor/autoload.php';

$server = IoServer::factory(
    new HttpServer(
        new WsServer(
            new Socket()
        )
    ),
    8088 // <--------------------------
);

$server->run();

• NB Run script using CLI - Command Prompt (Security measures)
• RUN php run to launch local web socket server

Notes (CLIENT)

// Create a new WebSocket.

//var socket  = new WebSocket('ws://127.0.0.1:8088');
var socket  = new WebSocket("ws://192.168.100.XX:8088");

var message = document.getElementById('message');

function transmitMessage() {
    socket.send( message.value );
}

socket.onmessage = function(e) {
    alert( e.data );
}

URL : http://localhost/websocket/ - use local tunnel / ngrok (Will work on same network)
