php获取google pr 值的代码

功能:对URL进行编码

参数说明:$web_url 网站URL,不包含"http://",例如phprm.com

php获取google pr 值的代码如下:

<?php
function HashURL($url) {
    $SEED = "Mining PageRank is AGAINST GOOGLE&#39;S TERMS OF SERVICE. Yes, I&#39;m talking to you, scammer.";
    $Result = 0x01020345;
    for ($i = 0; $i < strlen($url); $i++) {
        $Result^= ord($SEED{$i % 87}) ^ ord($url{$i});
        $Result = (($Result >> 23) & 0x1FF) | $Result << 9;
    }
    return sprintf("8%x", $Result);
}

功能:

获取pagerank参数说明:

$domain网站域名，不包含"http://", 代码如下:

function pagerank($domain) {
$StartURL = "http://toolbarqueries.google.com/tbr?client=navclient-auto&features=Rank:&q=info:";
// $StartURL = "http://www.google.com/search?client=navclient-auto&features=Rank:&q=info:";
$GoogleURL = $StartURL . $domain . ' &ch=' . HashURL($domain);
$fcontents = file_get_contents("$GoogleURL");
$pagerank = substr($fcontents, 9);
if (!$pagerank) return "0";
else return $pagerank;
}

OK, 用php获取谷歌PR值算法, 其实就这么简单, 自己去测试下吧, 上次, 谷歌的PR值查询接口更改, 上面的代码已经修改使用了谷歌PR查询的最新接口 .
