Is it possible to use PHP to detect and close popups that appear on a website?

It is not possible to use PHP alone to detect and close popups that appear on a website, as PHP is a server-side language and does not interact with the client-side browser. Popups are typically controlled using JavaScript, which is a client-side language. To detect and close popups, you would need to use JavaScript code within your website.
