What are the limitations of using PHP for displaying images in pop-up windows?

One limitation of using PHP for displaying images in pop-up windows is that PHP is a server-side language and cannot directly interact with the user's browser to create pop-up windows. To overcome this limitation, you can use JavaScript in conjunction with PHP to generate the necessary HTML and JavaScript code for displaying images in pop-up windows.

<?php
$imageUrl = 'image.jpg';
echo '<script>';
echo 'window.open("' . $imageUrl . '", "_blank", "width=400, height=400");';
echo '</script>';
?>
