What are the potential pitfalls of trying to implement JavaScript functionality in PHP for website navigation?

One potential pitfall of trying to implement JavaScript functionality in PHP for website navigation is that PHP is a server-side language, while JavaScript is a client-side language. This means that PHP cannot directly interact with the user's browser in real-time. To solve this issue, you can use PHP to generate the necessary JavaScript code and then output it to the client's browser.

<?php
// PHP code to generate JavaScript for website navigation
echo '<script>';
echo 'document.getElementById("myButton").addEventListener("click", function() {';
echo 'window.location.href = "newpage.php";';
echo '});';
echo '</script>';
?>
