How can PHP scripts be optimized to efficiently handle and display real-time data updates in a forum setting?

To efficiently handle and display real-time data updates in a forum setting using PHP scripts, you can implement AJAX polling or WebSocket technology. AJAX polling involves making periodic requests to the server to check for updates, while WebSocket allows for a persistent connection between the client and server for real-time communication. Both methods can help reduce server load and improve the responsiveness of the forum. 

// AJAX polling example
// In your forum page, use JavaScript to make periodic AJAX requests to check for updates
// Update the forum content dynamically based on the response from the server

<script>
setInterval(function() {
    $.ajax({
        url: 'check_updates.php',
        success: function(data) {
            // Update forum content with new data
        }
    });
}, 5000); // Polling interval of 5 seconds
</script>
```

```php
// WebSocket example
// Implement a WebSocket server in PHP to handle real-time communication with clients
// Use JavaScript WebSocket API in the forum page to establish a connection and receive updates

// PHP WebSocket server code
// Refer to a library like Ratchet for WebSocket server implementation

// JavaScript WebSocket client code in forum page
var socket = new WebSocket('ws://localhost:8080');
socket.onmessage = function(event) {
    // Handle real-time updates received from the server
};
