What are some alternative approaches to updating values in PHP forms without refreshing the page?

When updating values in PHP forms without refreshing the page, one common approach is to use AJAX to send the form data to a PHP script in the background and update the values dynamically on the page without reloading. This allows for a smoother user experience and eliminates the need for a full page refresh. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data
    $new_value = $_POST['new_value'];
    
    // Update database or perform any necessary actions
    
    // Return updated value to display on the page
    echo $new_value;
    exit;
}
?>
