What are the best practices for using DHTML in PHP to preload pages and prevent flickering?

To preload pages and prevent flickering when using DHTML in PHP, it's important to use AJAX to load content dynamically without refreshing the entire page. This can be achieved by preloading content in the background and then displaying it once it's fully loaded. Additionally, optimizing CSS and JavaScript files can help reduce flickering and improve page loading speed. 

<?php
// Preload content using AJAX
echo '<div id="preload" style="display:none;">';
echo file_get_contents('preload-content.html');
echo '</div>';
?>

<script>
// Display preloaded content
document.addEventListener('DOMContentLoaded', function() {
    document.getElementById('preload').style.display = 'block';
});
</script>
