How can PHP be integrated with JavaScript to achieve real-time data updates in a multiplayer online game scenario?

To achieve real-time data updates in a multiplayer online game scenario, PHP can be integrated with JavaScript using AJAX requests. PHP can handle the server-side logic and database operations, while JavaScript can handle the client-side interactions and update the game interface in real-time.

<?php
// PHP code to handle AJAX request for updating game data
if(isset($_POST['data'])) {
    // Update game data in the database
    $data = $_POST['data'];
    // Perform necessary operations
    // Return updated data
    echo json_encode($updatedData);
}
?>
