you can use session and post filename and file content to download page

session_start();
$_SESSION['filename'] = $filename
$_SESSION['file'] = $file
echo "Download File"

and in download.php use this code

session_start();
$filename = $_SESSION['filename'];
$file = $_SESSION['file'];
header("Content-Disposition: attachment; filename=$filename");
ob_clean();
flush();
echo $file;
