title: Switching themes in Drupal without the web interface
body: <p>I'm in the process of learning php and creating themes.</p>
  
  <p>Unfortunately, while I was editing a theme that i was currently using in drupal, I made a mistake in the theme such that nothing shows up anymore, even if i were to hit drupal/index.php. I want to change my broken drupal theme to a working one but i'm unable to do so because I can't even view the administration section.</p>
