title: Pulling random switch cases
body: <p>I have a switch function I want to be able to randomly pull cases from: </p>
  
  <pre><code>&lt;?php
      function peopleGet($name) {
          switch ($name) { 
  
              case 'gloria': 
              echo 'gloria';
              break;
  
              case 'benjamin': 
              echo 'benjamin';
              break;
  
              case 'callum': 
              echo 'callum';
              break;
          }
      }
  ?&gt;
  </code></pre>
  
  <p>I still need to be able to pull specific variables:</p>
  
  <pre><code>&lt;?php peopleGet('gloria'); ?&gt;
  </code></pre>
  
  <p>However, is it possible to use the same function to be able to pull random (no-repeating) cases?</p>
