I am generating docx and download from server.

private static function downloadFile($fileDir)
    header('Content-Description: File Transfer');
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename=' . basename($fileDir));
    header('Content-Transfer-Encoding: binary');
    header('Expires: 0');
    header('Cache-Control: must-revalidate');
    header('Pragma: public');
    header('Content-Length: ' . filesize($fileDir));

This is save function. if I open file in the temporary dir from server, it works. But after download, I have error "The file is damaged" . I try to restore the file and afrer restoring all ok. Where is error?

 header('Content-Description:File Transfer'); 
 header('Content-Type:application / octet-stream'); 
 header('Content-Disposition:  attachment; filename ='。basename($ fileDir)); 
 header('Cache-Control:必须 -  revalidate'); 
 header('Content-Length:'。filesize($ fileDir)); 
 readfile($ fileDir); 

这是保存功能。 如果我从服务器打开临时目录中的文件,它的工作原理。 但下载后,我有错误“文件已损坏”。 我尝试恢复文件,然后恢复所有确定。 哪里出错?

    Before readfile($fileDir), try to run ob_clean() and flush() to clean (erase) and flush the output buffer.

    Quoting from PHP's manual about flush():

    flush() may not be able to override the buffering scheme of your web server and it has no effect on any client-side buffering in the browser. It also doesn't affect PHP's userspace output buffering mechanism. This means you will have to call both ob_flush() and flush() to flush the ob output buffers if you are using those.
