Create a backend for a real-time chat system using PHP and WebSockets with the Ratchet library. This guide includes connection handling, message broadcasting, and error management.

This PHP snippet sets up a backend for a real-time chat system using WebSockets for communication. The code demonstrates how to handle incoming messages and send responses to all connected clients in real time.

The snippet integrates with Ratchet, a PHP library for working with WebSockets, to manage WebSocket connections and events. It includes a simple server setup that listens for new connections and message events.

Error handling is included to manage disconnects and errors in communication, ensuring the chat system remains robust and can recover from failures gracefully.

The code provides functionality to broadcast messages to all connected clients, which is essential for chat applications where messages need to be seen by all participants immediately.

This snippet is ideal for developers looking to implement real-time communication features in web applications or services.
