In PHP, what considerations should be taken into account when dynamically updating iframe content to ensure a seamless user experience?

When dynamically updating iframe content in PHP, it is important to ensure a seamless user experience by avoiding page reloads. One way to achieve this is by using AJAX to fetch and update the content of the iframe without refreshing the entire page. Additionally, make sure the content being loaded into the iframe is properly formatted and compatible with the iframe's dimensions to prevent layout issues. 

<?php
if(isset($_GET['url'])){
    $url = $_GET['url'];
    echo '<iframe src="'.$url.'" style="width:100%; height:100vh;"></iframe>';
}
?>
