What are the best practices for implementing real-time updates in PHP applications like chat functionality?

When implementing real-time updates in PHP applications like chat functionality, it is essential to use technologies like WebSockets or server-sent events (SSE) to achieve real-time communication between the server and client. These technologies allow for bi-directional communication, enabling instant updates without the need for constant polling. Additionally, consider using a library or framework that simplifies the implementation of real-time features to streamline the development process. 

// Example code snippet for implementing real-time updates using WebSockets in PHP

// Create a WebSocket server
$server = new \WebSocket\Server('0.0.0.0', 8000);

// Event listener for new connections
$server->on('connect', function($client) use ($server) {
    echo "New connection established\n";
});

// Event listener for incoming messages
$server->on('message', function($client, $message) use ($server) {
    echo "Message received: $message\n";

    // Broadcast the message to all connected clients
    foreach ($server->getClients() as $recipient) {
        $recipient->send($message);
    }
});

// Start the WebSocket server
$server->run();
