Description:

In my opinion it is difficult to send special HTTP headers.
If you create a File programaticly and want to send it to the user, you have to use something like:

<?php
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"file.csv\"");
header("Content-Length: ".strlen($csv));
?>

So I have written some classes to make it easier.
The same result of the upper example will be reached with the following:

<?php
$h = new HTTPHeader();
$h->ContentType()->ApplicationOctetStream();
$h->ContentDisposition()->Attachment()->Filename("file.csv");
$h->ContentLength($csv);
?>

If you think it would be a helpful class mail me.
