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'S TERMS OF SERVICE. Yes, I'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 .
