我的 mp4 文件有问题。Html5 Video Tag 可以用直接链接播放，但不能用 PHP Header 播放（Mp3 与 PHP Header 配合得很好）。我已经在 Stack 中尝试了几乎所有的解决方案，但仍然没有解决我的问题:(

好的！我已经解决了我的问题 :) 希望这会帮助任何和我有同样问题的人
Just use that code:
只需使用该代码：
$file = 'local_file';
$newfile = 'outFile';
if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($newfile));
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
flush();
readfile($file);
exit;
}

I think you've added unnecessary headers to your php file. Try this one:
我认为您在 php 文件中添加了不必要的标题。试试这个：
$local_file = 'z.mp4';
$size = filesize($local_file);
header("Content-Type: video/mp4");
header("Content-Length: ".$size);
readfile($local_file);
And a HTML code something like this
和一个像这样的 HTML 代码
<video width="480" height="320" controls>
<source src="mp4.php" type="video/mp4">
</video>
EDIT:This will also work for mp3 files when you change Content-Type header and html video type.
编辑：当您更改 Content-Type 标题和 html 视频类型时，这也适用于 mp3 文件。
<video width="480" height="320" controls>
<source src="mp3.php" type="audio/mpeg">
</video>
