PR值是google衡量网站的重要标准之一,今天就给大家一个用PHP查询网站的PR值的方法。

PR值是google衡量网站的重要标准之一,根据google提供的结果获取pr值,,如:
?client=navclient-auto&features=Rank:&q=info:phpddt.com&ch=8fabc62ea

复制代码 代码如下:


/*
*功能:对URL进行编码
*参数说明:$web_url 网站URL,不包含"http://"
*/
function HashURL($url)
{  
    $SEED = "Mining PageRank is AGAINST GOOGLE'S TERMS OF SERVICE. Yes, I'm talking to you, scammer.";
    $Result = 0x01020345;
    for ($i=0; $i    {
        $Result ^= ord($SEED{$i%87}) ^ ord($url{$i});
        $Result = (($Result >> 23) & 0x1FF) | $Result     }
    return sprintf("8%x", $Result);
}

/*
*功能:根据google提供的pr查询接口获取pagerank
*参数说明:$domain 网站域名,不包含"http://"
*/
function pagerank($domain)
{   
    $StartURL = "http://toolbarqueries.google.com/tbr?client=navclient-auto&features=Rank:&q=info:";
    $GoogleURL = $StartURL.$domain. '&ch='.HashURL($domain);
    echo $GoogleURL.'
';
    $fcontents = file_get_contents("$GoogleURL");
    $pagerank = substr($fcontents,9);
    if (!$pagerank) return "0";else return $pagerank;
}
echo pagerank("phpddt.com");
?>
