How can the use of document.write in PHP scripts impact the performance and functionality of embedded JavaScript code?

Using document.write in PHP scripts can impact the performance and functionality of embedded JavaScript code because document.write overwrites the entire document when it's called after the page has been loaded. This can cause issues with the execution of other JavaScript code on the page. To solve this issue, you can use JavaScript functions like document.createElement and appendChild to dynamically add content to the page without interfering with other scripts.

<?php
echo '<script>';
echo 'var newElement = document.createElement("p");';
echo 'var text = document.createTextNode("This is dynamically added content");';
echo 'newElement.appendChild(text);';
echo 'document.body.appendChild(newElement);';
echo '</script>';
?>
