WebSocket PHP handles each message separately - php

Question

I use Ratchet library to create websocket on php and I set a timeout of 10 seconds to return a message to the client, then I see that it will wait for the first message to be processed before processing the next message, how to make each message it will process always without waiting for the previous message
socket.php
<?php
namespace MyApp;
use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;
class Socket implements MessageComponentInterface {
protected $clients;
public function __construct() {
$this->clients = new \SplObjectStorage;
}
public function onOpen(ConnectionInterface $conn) {
// Store the new connection to send messages to later
$this->clients->attach($conn);
echo "New connection! ({$conn->resourceId})\n";
}
public function onMessage(ConnectionInterface $from, $msg) {
$time = date("H:i:s");
sleep(10);
$numRecv = count($this->clients) - 1;
echo sprintf('Connection %d sending message "%s"' . "\n"
, $from->resourceId, $msg);
$from->send("Server Reply: ".$time);
}
public function onClose(ConnectionInterface $conn) {
// The connection is closed, remove it, as we can no longer send it messages
$this->clients->detach($conn);
echo "Connection {$conn->resourceId} has disconnected\n";
}
public function onError(ConnectionInterface $conn, \Exception $e) {
echo "An error has occurred: {$e->getMessage()}\n";
$conn->close();
}
}
run.php
<?php
use Ratchet\Server\IoServer;
use Ratchet\Http\HttpServer;
use Ratchet\WebSocket\WsServer;
use MyApp\Socket;
require 'vendor/autoload.php';
require "socket.php";
$server = IoServer::factory(
new HttpServer(
new WsServer(
new Socket()
)
),
8765
);
$server->run();
