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:
http://toolbarqueries.google.com.hk/tbr?client=navclient-auto&features=Rank:&q=info:phpddt.com&ch=8fabc62ea

 

<?php /*
*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&rsquo;S TERMS OF SERVICE. Yes, I&rsquo;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 ';
    $fcontents = file_get_contents("$GoogleURL");
    $pagerank = substr($fcontents,9);
    if (!$pagerank) return "0";else return $pagerank;
}
echo pagerank("phpddt.com");
?>
