在我的服务器中，MIME类型“ application / octet-stream”已切换为“ text / html”。 怎么预防？

Question

I am trying to download my .mp3 file from server but when I pass below code , it prints the file at browser screen in binary converting Content-Type: text/html;charset=UTF-8 .

If I tried same code to other server, It runs successfully with Content-Type: application/octet-stream . So I can say code is 100% valid (code is in PHP ).

So Is this problem in server configuration or any other issue? Please help me to resolve this problem.

<?php 
set_time_limit(0);
$url = 'https://abcdefgh.s3.amazonaws.com/audio/1431428586_z3PtL.mp3';
$file = basename($url);
$fp = fopen($file, 'w');
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_FILE, $fp);
$data = curl_exec($ch);
curl_close($ch);
fclose($fp);
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
flush();
readfile($file);
exit;
?>

yes, it could be the server configuration. firstly, try to upload your original mp3 to the server and access it like http://yourserver.com/file.mp3 . If you can, then something wrong with your php, if you cannot - tweak the server.
