How can one effectively add and remove classes in PHP to style elements dynamically?

To dynamically add and remove classes in PHP to style elements, you can use the `classList` property in JavaScript. This property allows you to manipulate the classes of an element by adding, removing, or toggling them based on certain conditions. By using JavaScript within your PHP code, you can easily achieve dynamic styling of elements on your webpage.

<?php
// PHP code to dynamically add and remove classes in HTML elements
echo "<div id='myElement' class='initialClass'></div>";
echo "<script>";
echo "var element = document.getElementById('myElement');";
echo "element.classList.add('newClass'); // Add a new class dynamically";
echo "element.classList.remove('initialClass'); // Remove an initial class dynamically";
echo "</script>";
?>
