What code do you need to add in PHP to automatically have the browser download a file to the local machine when a link is visited?

I am specifically thinking of functionality similar to that of download sites that prompt the user to save a file to disk once you click on the name of the software?

Send the following headers before outputting the file:

header("Content-Disposition: attachment; filename=\"" . basename($File) . "\"");
header("Content-Type: application/octet-stream");
header("Content-Length: " . filesize($File));
header("Connection: close");

@grom: Interesting about the 'application/octet-stream' MIME type. I wasn't aware of that, have always just used 'application/force-download' :)
