title: Force-Download with php on Amazon S3
body: <p>I am trying to use <a href="http://code.google.com/p/amazon-s3-php-class/" rel="noreferrer">http://code.google.com/p/amazon-s3-php-class/</a> to force-dowload files from AWS S3. I have an mp3 that I want people to "play" or "download." By default the when you access the file directly on s3 it begins to play in the browser. I need to add an option to actually download. I have Googled and found came up with nothing. I conceptually know what needs to happen but don't know how to produce it php. I know I need to modify the headers to  Content-Disposition: attachment. Any help would be greatly appreciated.</p>
  
  <p>Thanks,
  Michael</p>
