用下面两个函数你也可以做个PR查询服务了^^


function app_hash_url($url){
    $seed="Mining PageRank is AGAINST GOOGLE'S TERMS OF SERVICE.";
    $result=0x01020345;
    for($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);
}
 
function get_pr($url){
    $PR_CH=app_hash_url($url);
    $url='http://toolbarqueries.google.com/tbr?client=navclient-auto&features=Rank&q=info:'.$url.'&ch='.$PR_CH;
    $prtext=file_get_contents($url);
    if($prtext!=""){
    $pr=explode(":",$prtext);
    return trim($pr[2]);
    }else{
    return 0;
    }
}
用法

echo get_pr("www.oicqzone.com")
