How can z-index be utilized in PHP to manage the layering of elements like thumbnails and enlarged images?

When managing the layering of elements like thumbnails and enlarged images in PHP, you can use z-index to control the stacking order of these elements. By setting a higher z-index value to the enlarged image, it can be displayed on top of the thumbnails. This can be achieved by dynamically adding a style attribute with the z-index property to the HTML elements representing the thumbnails and enlarged images. 

<?php
$thumbnailStyle = "style='z-index: 1'";
$enlargedImageStyle = "style='z-index: 2'";
echo "<img src='thumbnail.jpg' $thumbnailStyle />";
echo "<img src='enlarged.jpg' $enlargedImageStyle />";
?>
