What are the benefits of hosting a WebSocket server on a separate subdomain and how does it affect the overall architecture of a web application?

Hosting a WebSocket server on a separate subdomain can improve the overall performance and scalability of a web application. By separating the WebSocket server from the main application server, it allows for better resource management and load balancing. Additionally, it provides better security as WebSocket traffic can be isolated and managed separately. 

// Example PHP code to connect to a WebSocket server on a separate subdomain
$serverUrl = 'wss://websocket.example.com';
$socket = new WebSocket($serverUrl);
$socket->send('Hello, WebSocket server!');
$response = $socket->receive();
echo $response;
