Simple WebSocket server

use Ollyxar\WebSockets\{
    Server as WServer,
    Ssl as Wsl,
    Worker as Handler,
    Frame as WFrame
};

class MyHandler extends Handler
{
    /**
     * MyHandler constructor.
     * @param $server
     * @param $master
     */
    public function __construct($server, $master)
    {
        parent::__construct($server, $master);
        echo "I'm: #{$this->pid}\n";
    }

    /**
     * @param $client
     */
    protected function onConnect($client): void
    {
        $this->sendToAll(WFrame::encode(json_encode([
            'type'    => 'system',
            'message' => 'User {' . (int)$client . '} Connected.'
        ])));
    }

    /**

    protected function onClose($clientNumber): void
    {
        $this->sendToAll(WFrame::encode(json_encode([

        $message = json_decode($message);
        $userName = $message->name;
        $userMessage = $message->message;

        $response = WFrame::encode(json_encode([

            'name'    => $userName,

        ]));

        $this->sendToAll($response);
    }

Communicate with server outside the wss protocol

use Ollyxar\WebSockets\Server as WServer;
use Ollyxar\WebSockets\Frame;

$socket = socket_create(AF_UNIX, SOCK_STREAM, 0);
socket_connect($socket, WServer::$connector);

$data = new stdClass();
$data->type = 'system';
$data->message = 'hello World!';
$msg = Frame::encode(json_encode($data));

socket_write($socket, $msg);
socket_close($socket);
