Google PageRank查询

域名：

<br /> <?php教程<br /> if($q2<>""){<br /> echo $q2;<br /> }else{<br /> echo "www.111cn.net tool.111cn.net down.111cn.net baidu.com google.com";<br /> }<br /> ?><br />

/> 查询二级域名PR /> 鉴别真假

查 询

require_once '../ad/mid.php';
if($q2==''){
?>

工具说明

请输入域名，如chaxun.la。
多域名查询请每行输入一个域名，域名没有个数限制！
查询二级域名PR：将查询该域名的二级域名的PR。（二级域名通过查询本站数据库教程获得，并不全面！）
鉴别真假：将鉴别该域名的PR是否是劫持其它网站的PR。
