PHP Streaming MP3

Question

I have a very similar situation to the person who asked: Can I serve MP3 files with PHP? Basically I am trying to protect mp3 files from direct download, so users have to go

Answer 1

Here's what did the trick.

$dir = dirname($_SERVER['DOCUMENT_ROOT'])."/protected_content";
$filename = $_GET['file'];
$file = $dir."/".$filename;

$extension = "mp3";
$mime_type = "audio/mpeg, audio/x-mpeg, audio/x-mpeg-3, audio/mpeg3";

if(file_exists($file)){
    header('Content-type: {$mime_type}');
    header('Content-length: ' . filesize($file));
    header('Content-Disposition: filename="' . $filename);
    header('X-Pad: avoid browser bug');
    header('Cache-Control: no-cache');
    readfile($file);
}else{
    header("HTTP/1.0 404 Not Found");
}
