php - How to create a link that triggers file download?

When a user clicks a "Download PDF" link, I would like for the download prompt to appear and for the user to be able to download the file.

Currently, the user is just transferred to the address of the PDF file.

For example:

<a..[what goes here??]..>Download PDF</a>

It seems that there's a combination of JavaScript & PHP needed to do this.

Can anyone give an example?

Redirect to a PHP page with this code on it:

<?php
header('Content-disposition: attachment; filename=movie.mpg');
header('Content-type: video/mpeg');
readfile('movie.mpg');
?>

your <a href code will need to point to a specific page, and readfile will call your resource

Just as a side note, I do agree that you should not override a browsers settings, but sometimes when the boss asks, you just have to do.
