title: PHP doesn't run through Snow Leopard Web Sharing
body: <p>I've followed all the tutorials and uncommented the relevant lines in httpd.conf, but PHP files do not render under Web Sharing.</p>
  
  <p>The server just serves up the source code instead of running it.</p>
  
  <p>I know that PHP works, because I can run it straight from the Terminal using the "php" command.</p>
  
  <p>What is happening here?</p>
