title: how to do this.. backwards?
body: <p>I currently have:</p>
  
  <pre><code>$i = 1;
  while {
    echo $i;
    $i++;
  }
  </code></pre>
  
  <p>And it shows:</p>
  
  <pre>
  1
  2
  3
  4 etc..
  </pre>
  
  <p>How would I make it display backwards?</p>
  
  <p>For example</p>
  
  <pre>
  4
  3
  2
  1 etc..
  </pre>
  
  <p>I basically want to do the exact same thing but flip it around.</p>
