title: Nested if statements declaring return false for each one
body: <p>Say I have the following code:</p>
  
  <pre><code>function a() {
      if ($a) {
          if ($b) {
              if ($c) {
                  // do something
              }
              return FALSE
          }
          return FALSE;
      }
      return FALSE;
  }
  </code></pre>
  
  <p>In this instance do I need all the return falses or will it sort of cascade to the last one if I remove both the inner ones?</p>
  
  <p>Thanks</p>
