Don't think you'll be able to do this, AFAIK. Leastways, if you do, it
won't be with php, which is strictly server-side.

With php, the best I think you can do is report the total bytes to of
the object to be transfered in the headers and the browser will report
file transfer progress if it's supports that. IE and Safari do this.
But having php talk to the browser and continuously report back periodic
progress isn't possible.

You might start looking into writing a java-based client-server pair
that can do the handshaking, file transfer, and report on progress.
