功能:對URL進行編碼
參數說明:$web_url 網站URL,不包含"http://",例如Vevb.com
php獲取google pr 值的代碼如下:
- function HashURL($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;
- }//開源代碼Vevb.com
- return sprintf("8%x", $Result);
- }
功能:獲取pagerank
參數說明:$domain 網站域名,不包含"http://",代碼如下:
- 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獲取谷歌PR值算法,其實就這么簡單,自己去測試下吧,上次,谷歌的PR值查詢接口更改,上面的代碼已經修改使用了谷歌PR查詢的最新接口.
