No progress bar in IE8 while executing the download using PHP

Question

I am giving downloads to user using the PHP code below but when user downloading they are not able to see the progressbar in IE8 when clicked on save button. Please solve this. Thanks in advance.

header('Content-Description: Songsbin.com - Downlaod');
header('Content-type: audio/mpeg');
header('Content-Disposition: attachment; filename='.$filename1);
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: '.filesize($file));
ob_clean();
flush();
readfile($file);

Answer 1

Your code is correct, I also tried and both in Chrome and IE8 it works good...

if you succeed to download the file check that filesize($file) returns a correct output..
