I’m working on my school project and I’m trying to output a mp3 file

  • 0

I’m working on my school project and I’m trying to output a mp3 file using PHP but apparently it just outputs some corrupt file and I have no clue why. I browsed the entire net to find a solution, but no.

<?php
$filename = 'audio/1/1.mp3';

if(file_exists($filename)) {
    header('Content-Type: audio/mpeg');
    header('Content-Disposition: filename="test.mp3"');
    header('Content-length: '.filesize($filename));
    header('Cache-Control: no-cache');
    header("Content-Transfer-Encoding: chunked"); 

    readfile($filename);
} else {
    header("HTTP/1.0 404 Not Found");
}
?>

Can anyone explain this to me? That would be totally awesome!

    Well the answer was way off and it wasn’t my script. Before any HTML tag I load all content, if custom headers are defined I only show the content (retrieved from templates)

    <?php
//get stuff
if(empty($page->customHeader)): ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title><?php print $page->title ?></title>
</head>

<body>
<div class="container">
    <div class="header">
    </div>

    <div class="content">        
        <?php print $page->content ?>
    </div>

    <div class="footer">
    </div>
</div>
</body>
</html>
<?php else:
    print $page->content;
endif; ?>

    For the templates i use ob_get_contents(), so in the actual template I echo/print data. For some reason ob_get_contents() doesn’t fetch that properly so that’s where it went wrong.

    Now I define my headers in an array and the path of the content in another variable and call that.

    ...
</html>
<?php else:
    foreach($page->customHeader as $header) {
        header($header, true);
    }

    readfile($page->headerContent);
endif; ?>

    Long story short:
    ob_get_contents() doesn’t get binary content.

    Thanks guys, definately going to give you thumbs up for the efford and rather useful information!
