<?
$filename = "my.txt";
$data = "Filens indhold";
$size = strlen($data);
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
header("Content-Disposition: attachment; filename=".basename($filename).";");
header("Content-Transfer-Encoding: 7bit");
