  <?PHP if (isset($result)): ?>
    <div class="result">
      <h3>Summary</h3>
      <?PHP print $result['title']; ?> got a PageSpeed score of <b><?PHP print $result['score']; ?></b> (out of 100).
      <div>Title: <?PHP print $result['title']; ?></div>
      <div>score: <?PHP print $result['score']; ?></div>
      <div>Number of Resources: <?PHP print $result['pageStats']['numberResources']; ?></div>
      <div>Number of Hosts: <?PHP print $result['pageStats']['numberHosts']; ?></div>
      <div>Total Request Bytes: <?PHP print $result['pageStats']['totalRequestBytes']; ?></div>
      <div>Number of Static Resources: <?PHP print $result['pageStats']['numberStaticResources']; ?></div>
      <pre><?PHP var_dump($result); ?></pre>
    </div>
    </div>
</body>
</html>

解决方法:

缺少<？PHP endif; ？&GT对于

<?PHP if (isset($result)): ?>

它可能应该在第一个< / div>之后,这是：

</div>
<?PHP endif; ?>
</div>
