What are the advantages of using JavaScript over PHP for implementing interactive features like playing music on mouseover?

JavaScript is better suited for implementing interactive features like playing music on mouseover because it can easily manipulate the DOM in real-time without requiring a page refresh. PHP, on the other hand, is a server-side language and is not ideal for handling client-side interactions. By using JavaScript, you can create a smoother and more responsive user experience when playing music on mouseover.

// PHP code snippet
// This code snippet demonstrates how PHP can be used to output JavaScript code that plays music on mouseover

<?php
echo '<script>';
echo 'document.getElementById("audio").onmouseover = function() {';
echo 'document.getElementById("audio").play();';
echo '}';
echo '</script>';
?>
