Detecting Browser exit in PHP

I have some user related files in my server and I want them to be deleted when user closes the browser or leaves my page. Is it possible? Is there any way to do it?

Answer 1

Not just with PHP.

PHP runs server-side, and is far done processing your page by the time the user will have a chance to close their browser. You could technically detect if PHP was still processing the page and the user closes it, with a specific configuration. However, it is not ideal. See connection_aborted().

What you need to do is set up a long-polling connection with JavaScript, and monitor it server-side. You will then get an idea for when that window is closed. That connection could be made to your PHP script, allowing PHP to check connection_aborted(). Note that you will need to set up ignore_user_abort() for this to work, or configure PHP.ini accordingly.
