when you use x-accel.

when you use readfile i would expect you have to provide -all- the headers. :)

Right now this is all I have for mine and it works like a charm:

header("Content-Disposition: attachment;
filename=\"".urldecode(basename($file))."\";");
header("Content-Type: application/force-download");
header("X-Accel-Redirect: $file_uri");
