写完后刷了下，就发现有人回答了我用到的函数。
下面是我的代码：
//Powered by www.hejunbin.com$html_body = '<div class="list_enter_ipad_scroll">
<ul class="list_enter_ipad" id="footerScroller" style="width:1370px">              <li><a href="http://ipad.qq.com/" class="tencentIpad">首页</a></li>

<li><a href="http://ipad.qq.com/variety/index.htm" class="varietyIpad">综艺</a></li>     </ul></div>';
$hejunbin = array();
$html_body = preg_replace('#(href=")(.*?)(")#e',
              "stripslashes('\\1').hejunbin('\\2').stripslashes('\\3')",
              $html_body);
function hejunbin($value) {
global $hejunbin;
$key = microtime(true).mt_rand(10, 99).'.html';
$hejunbin[$key] = $value;

return $key;
}echo '<pre>';
echo $html_body;
print_r($hejunbin);
