Answer 1

this is what I did, has some improvements on the same idea.

adds 2 functions that you can call elsewhere: send_to() and multicast().

namespace mine;
use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;

class ws implements MessageComponentInterface {
    protected $clients;
    protected $clientids;

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

    public function multicast($msg) {
        foreach ($this->clients as $client) $client->send($msg);
    }

    public function send_to($to,$msg) {
        if (array_key_exists($to, $this->clientids)) $this->clientids[$to]->send($msg);
    }

    public function onOpen(ConnectionInterface $conn) {
        $socket_name = "{$conn->resourceId}@{$conn->WebSocket->request->getHeader('X-Forwarded-For')}";
        $this->clients->attach($conn,$socket_name);
        $this->clientids[$socket_name] = $conn;
    }

    public function onMessage(ConnectionInterface $from, $msg) {
        $this->multicast($msg);
    }

    public function onClose(ConnectionInterface $conn) {
        unset($this->clientids[$this->clients[$conn]]);
        $this->clients->detach($conn);
    }

    public function onError(ConnectionInterface $conn, \Exception $e) {
        $conn->close();
    }
}
