php-symfonyHow to use websockets in PHP Symfony?
Websockets can be used in PHP Symfony to create real-time applications. To use websockets, the Ratchet library can be used.
Example code
<?php
use Ratchet\Server\IoServer;
use Ratchet\Http\HttpServer;
use Ratchet\WebSocket\WsServer;
use MyApp\Chat;
$server = IoServer::factory(
new HttpServer(
new WsServer(
new Chat()
)
),
8080
);
$server->run();
