What are the limitations of using PHP to detect popups and close them?

Detecting and closing popups using PHP is not possible because PHP is a server-side language and does not have the ability to interact with client-side elements like popups. To handle popups, you would need to use JavaScript, which is a client-side language that can manipulate the browser's DOM. 

// PHP code cannot detect or close popups, but you can use JavaScript to achieve this
echo "<script>window.close();</script>";
