Here's what works for me. I haven't tested your case with IE but you
might give it a try.

header('Content-Description: File Transfer');
header('Content-Type: application/pdf');
header('Content-Length: ' . filesize($file));

// to download
header('Content-Disposition: attachment; filename=' . basename($file));

// to open in browser
//header('Content-Disposition: inline; filename=' . basename($file));

readfile($file);
