What are the limitations of using PHP to update frames on a webpage?

One limitation of using PHP to update frames on a webpage is that PHP is a server-side language and cannot directly manipulate the client-side frames. To work around this limitation, you can use PHP to generate the necessary JavaScript code that will update the frames on the client-side. 

<?php
// PHP code to generate JavaScript code to update frames on a webpage
echo '<script>';
echo 'parent.frames["frame_name"].location.href = "new_url.php";';
echo '</script>';
?>
