What are some best practices for real-time data updates in PHP forms after submission?

When dealing with real-time data updates in PHP forms after submission, one best practice is to use AJAX to asynchronously update the form without requiring a full page reload. This allows for a smoother user experience and faster response times. Additionally, you can utilize JavaScript to dynamically update the form elements based on the submitted data. 

// PHP code for updating form data in real-time after submission

// Check if form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data here
    
    // Update form elements using JavaScript
    echo '<script>';
    echo 'document.getElementById("form_element_id").value = "new_value";';
    echo '</script>';
}
