Google谷歌PageRank值PHP查询程序

不说废话了直接上代码,效果和网络上查询到的一样!
index.php
<?php
include('pagerank.php');
$ips = array('216.239.59.18','209.85.135.100','66.249.89.99');
$pr=0;
for($i=0;$i<count($ips);$i++)
{
$pr = getPageRank($ips[$i],'http://域名/'); //可以使用 $_POST提交

if($pr>-1) break;
}
echo '我的PR为<img src="images/'.$pr.'.gif"/>';
?>
