To update the src attribute of an iframe using PHP without affecting the rest of the page content, you can use AJAX to send a request to a PHP script that will return the new URL for the iframe. Then, you can use JavaScript to update the src attribute of the iframe with the new URL without reloading the entire page.

<?php
// This PHP script will return the new URL for the iframe
$newUrl = "new_url_here";

echo $newUrl;
?>
