In what scenarios would it be more efficient to use Ajax alongside PHP for real-time data updates on a webpage?

When you want to update specific parts of a webpage without refreshing the entire page, it is more efficient to use Ajax alongside PHP for real-time data updates. This is especially useful for scenarios like live chat applications, dynamic content loading, or real-time notifications. 

<?php
// PHP code to handle the Ajax request and update data
if(isset($_POST['data'])) {
    // Process the data received from the Ajax request
    $data = $_POST['data'];
    
    // Update database or perform any necessary operations
    
    // Return updated data as response
    echo json_encode(['success' => true, 'message' => 'Data updated successfully']);
    exit;
}
?>
