If I understand your question correctly, you cannot. PHP works on the
server-side so once you've sent your HTTP response request, you are no
longer in control. Besides, I don't know any downloading tool that
doesn't already show a progress bar to the user. Even wget does so.

You can of course track how much data *you* have sent, but that
doesn't mean the client has downloaded all of it. It may for instance
be that the client didn't finish downloading or that it is downloading
slower than you are sending.
