Is it possible to use PHP to modify a DHTML page server-side without causing flickering?

When using PHP to modify a DHTML page server-side, the issue of flickering can occur when the page is constantly reloading or refreshing. To solve this issue, you can use AJAX to dynamically update specific parts of the page without causing a full page reload. This allows for a smoother user experience without any flickering.

<?php
// Sample PHP code snippet using AJAX to update a specific element on a DHTML page without causing flickering

// Check if the AJAX request is being made
if(isset($_POST['data'])){
    // Process the data received from the AJAX request
    $newContent = $_POST['data'];

    // Update the specific element on the page with the new content
    echo $newContent;
    exit;
}
?>
