title: What exactly does || mean?
body: <pre><code>return (empty($neededRole) || strcasecmp($role, 'admin') == 0 || strcasecmp($role, $neededRole) == 0);
  </code></pre>
  
  <p>What exactly does the || mean in this statement? Can someone put this in english for me. </p>
  
  <p>I promise I've googled this but I guess I don't know what to google for because I can't find anything.</p>
  
  <p>thanks:)</p>
