How can the PHP code be modified to work with the document.write function in Javascript?

The issue is that PHP code cannot directly interact with the `document.write` function in JavaScript because PHP is executed on the server side while JavaScript is executed on the client side. To solve this, you can use PHP to output JavaScript code that utilizes the `document.write` function to display content on the client side.

<?php
// PHP code to output JavaScript using document.write
echo '<script>';
echo 'document.write("Hello, World!");';
echo '</script>';
?>
