title: How to generate a QR code and a downloadable link in php
body: <p>I would like to create a program that generates a QR code based on a URL (data from a database).
  The QR code will not be stored or saved, but only downloadable via a link on the page displaying the QR code.
  All in PHP :)
  Could someone help me ?
  I haven't found my answer for the downloadable link :)</p>
