title: PHP sqlsrv_get_field returns always blank
body: <p>I'm wondering why <code>sqlsrv_get_field($stmt,0)</code> is not working: it always returns blank while for example sqlsrv_fetch_array finds results. For example:</p>
  
  <pre><code>while ($row = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_ASSOC)) {
      $title = $row['title'];
  };
  </code></pre>
  
  <p>this is returning data for the same query.</p>
