title: why does the PHP Manual say that fetch() doesn't exist
body: <p>in PHP, it's apparently possible to do the following (when working with a mySQL PDO connection)</p>
  
  <pre><code>while ($row = $result-&gt;fetch())
     {
                             }
  </code></pre>
  
  <hr>
  
  <p>However, the PHP Manual says that <code>fetch()</code> doesn't exist:</p>

  <p>What's going on? And how can I better learn to navigate the PHP Manual?</p>
