title: PHP Zip 3 small text files and force download
body: <p>My website writes 3 small text files based on users information and then presents these 3 files as links that they must "right click" and save to their desktop.</p>
  
  <p>I would like to keep that, but also somehow offer a way to zip these 3 small files up and force download.  And I don't want to save the zip file on the server either.  Can this be done and how?</p>
  
  <p>Thanks!</p>
