Output mp3 with php
提问by Tim S.
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.
我正在处理我的学校项目，我正在尝试使用 PHP 输出一个 mp3 文件，但显然它只是输出了一些损坏的文件，我不知道为什么。我浏览了整个网络以找到解决方案，但没有。
<?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!
任何人都可以向我解释这一点吗？那真是太棒了！

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)
嗯，答案还很遥远，这不是我的剧本。在我加载所有内容的任何 HTML 标签之前，如果定义了自定义标题，我只显示内容（从模板中检索）
<?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 $page->content;
endif; ?>
For the templates i use ob_get_contents(), so in the actual template I echo/print data. For some reason ob_get_contents() doesn't fetch that properly so that's where it went wrong.
对于模板，我使用 ob_get_contents()，因此在实际模板中我回显/打印数据。由于某种原因 ob_get_contents() 不能正确获取，所以这就是出错的地方。
Now I define my headers in an array and the path of the content in another variable and call that.
现在我在一个数组中定义我的标题，在另一个变量中定义内容的路径并调用它。
...
</html>
<?php else:
foreach($page->customHeader as $header) {
header($header, true);
}
readfile($page->headerContent);
endif; ?>
Long story short: ob_get_contents() doesn't get binary content.
长话短说：ob_get_contents() 不获取二进制内容。
Thanks guys, definately going to give you thumbs up for the efford and rather useful information!
谢谢你们，肯定会给你竖起大拇指，因为它提供了非常有用的信息！

header('Content-Disposition: inline;filename="test.mp3"');
That's what you're missing in your header() (you had no "inline" specified). Content-Transfer-Encoding should be "binary", not "chunked".
这就是您在 header() 中缺少的内容（您没有指定“内联”）。内容传输编码应该是“二进制的”，而不是“分块的”。
Edit: use "inline" if you want it to be displayed within the browser (if capabilities exist) or "attachment" if you want to force download.
编辑：如果您希望它在浏览器中显示（如果功能存在）或“附件”如果您想强制下载，请使用“内联”。

can you try replace
你可以尝试更换吗
header("Content-Transfer-Encoding: binary"); 符合 header("Content-Transfer-Encoding: chunked");
