我对 PHP 很陌生,它不是我的域,但是现在我需要从网站中提取某个值,我在互联网上查找并找到了我根据需要实现的以下功能:

          <?php
          $curl_handle=curl_init();
          curl_setopt($curl_handle,CURLOPT_URL,'http://www.indiagoldrate.com/gold-rate-in-mumbai-today.htm');
          curl_setopt($curl_handle,CURLOPT_CONNECTTIMEOUT,2);
          curl_setopt($curl_handle,CURLOPT_RETURNTRANSFER,1);
          $buffer = curl_exec($curl_handle);
          curl_close($curl_handle);
          if (empty($buffer))
          {
              print "Sorry, example.com are a bunch of poopy-heads.<p>";
          }
          else
          {
              print $buffer;
          }
          ?>

到目前为止,我可以检索整个页面,但我只对所述页面中的一个值感兴趣,我需要如何做的想法?

我需要的网页代码:(简单查看源码)

      <tr>
<td>MUMBAI<BR>Thu, Jul 25th, 2013</td>
<td><TABLE class="innerTable">
<TR>
    <TD>1g </TD>
    <TD>Rs. 2,595</TD>
</TR>

    <TD>8g</TD>
    <TD>Rs. 20,760</TD>

<TR>

</TABLE></td>

获取 simple_dom_html.php 文件并包含它。

$html = str_get_html($buffer);
$html->find('any class etc');
