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($fileDir));
readfile($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?
