How to delete a client side file using PHP?

Question

I have a PHP app and I need to delete a client-side file. How can I achieve that?

I'm new to PHP. Hope someone can help me.

Answer 1

You can't, browsers won't allow it, full stop.

_{You could if you wrote a browser/ActiveX/Java plugin that has that kind of access and got the user to install it, but please don't.}

Answer 2

You can't do this for obvious security reasons. PHP is server side only.
