我有一些不在 Web 根目录中的文件需要下载。所以我有一个使用下面的脚本来下载请求的文件。问题是，我下载的每个文件都损坏了？这些文件没问题，因为如果我使用 FTP 下载，它们会打开。以下是传递的标头：

header("Cache-Control: public"); // needed for i.e.
header("Content-Type: " . $download[0]['mime']);

Here is an example of headers used for that:
http://php.net/manual/en/function.readfile.php
这是用于此的标题示例：http:
//php.net/manual/en/function.readfile.php
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));
