How can PHP developers effectively troubleshoot and debug issues related to opening images in pop-up windows using PHP scripts?

Issue: When trying to open images in pop-up windows using PHP scripts, developers may encounter issues with the image not displaying correctly or the pop-up window not opening at all. To troubleshoot and debug these issues, developers can check for errors in the PHP script, ensure that the image path is correct, and verify that the pop-up window is being triggered properly.

<?php
// Sample PHP code to open an image in a pop-up window

$imagePath = 'path/to/image.jpg';

echo '<script>';
echo "window.open('$imagePath', '_blank', 'width=500, height=500')";
echo '</script>';
?>
