提供一款查询收录时常用的google正则表达式功能哦，我们是取得内容然后再正则出我们想要的内容，再在本地输出。

<?php
$TheUrl="http://www.google.cn/search?q=+site:".$q."&num=20&complete=1&hl=zh-CN&lr=&newwindow=1&as_qdr=".$t."&start=".$p."&sa=N";
    $TheThie=GetPage($TheUrl);
}
$TheBody=GetContent($TheThie,"<div id=res class=med>","<div id=bsf style");
$TheBody=iconv( "UTF-8", "gb2312//IGNORE" , $TheBody);
$TheBody=str_replace("<!--z--><p><i>","<!--z--><!--<p><i>",$TheBody);
$TheBody=str_replace('<br clear="all"/>','<br clear="all"/>',$TheBody);
$TheBody=preg_replace('<a href="/search?num=20(.+?)amp;as_qdr=(.+?)&amp;q=site:(.+?)&amp;start=(.+?)&amp;sa=N">','a href=?q=$3&t=$2&p=$4>&nbsp;&nbsp;&nbsp;&nbsp;<!--z--',$TheBody);
$TheBody=str_replace("该网站可能含有恶意软件，有可能会危害您的电脑。","",$TheBody);
$TheBody=str_replace("/interstitial?url=","",$TheBody);
$TheBody=str_replace("- <nobr>","",$TheBody);
$TheBody=str_replace("类似网页","",$TheBody);
$total=GetContent($TheThie,"</b></div><p>","</b> - <b>");
$total=iconv( "UTF-8", "gb2312//IGNORE" , $total);
$total=GetContent($total,"有 <b>","</b> 项");
$total=str_replace("有 <b>","",$total);
