How can you nest three tags within each other in PHP?

To nest three tags within each other in PHP, you can simply echo the tags within each other in the desired order. For example, you can nest a div tag within a p tag within a span tag by echoing them in the correct order. This allows you to create nested HTML elements within your PHP code.

<?php
echo "<span><p><div>This is a nested div within a nested p within a nested span.</div></p></span>";
?>
