How about just....

$file = 'some_file.exe';

$_size = filesize($_file);
header('Content-Type: binary/octet-stream');
header('Content-Length: '.$_size);
header('Content-Disposition: attachment; filename="' . basename($file) . '"; size=" . $_size);

@readfile($file);

Note: see the comment about some issues with binary files, however.

You should use readfile instead of echoing the read contents. I don't think this is really what the OP is asking for though.

@deceze: It's funny (and probably due to fatigue) I was thinking file() first (knew that wasn't right) then went to file_get_contents(). readfile() is, you're right, the better fit. However, I was more just showing that you'd do a combo between headers and outputting content to get the desired result.
