How to detect when a user has successfully finished downloading a file in php

Question

I\'ve got a php page which handles requets for file downloads. I need to be able to detect when a file has been downloaded successfully. How can this be done? Perhaps there\

Answer 1

What Treb said, but I should add that you can check if the client is still listening during download with connection_status().

Don't forget to flush() after you've written data to the client, it helps in detecting if the connection is still up.
