An easier way would be have the link go to another PHP script, which
generates the text content, and then serves it as an attachment, so no
need to save anything to disk.

e.g.

In A.html
=========

<A href="B.php">Download</A>


In B.php
========

<?php

header('Content-type: text/plain');
header('Content-Disposition: attachment; filename="stuff.txt"');


echo "Whatever dynamically generated stuff you want!!";
....

?>
