Updated Php code to query PageRank from Google

Thanks very much to MyVodaFone at DP for this code. It’s been very useful for me. I know that there are a lot of sites with the infamous “pagerank.php” code, but that died a month or so ago I’m told. Here is the new contents of pagerank.php. You know what to do with it!

<?php function StrToNum($Str, $Check, $Magic) {     $Int32Unit = 4294967296;     $length = strlen($Str);     for ($i = 0; $i < $length; $i++) {         $Check *= $Magic;           if ($Check >= $Int32Unit) {             $Check = ($Check - $Int32Unit * (int) ($Check / $Int32Unit));             $Check = ($Check < -2147483648) ? ($Check + $Int32Unit) : $Check;         }         $Check += ord($Str{$i});     }     return $Check; } function HashURL($String) {     $Check1 = StrToNum($String, 0x1505, 0x21);     $Check2 = StrToNum($String, 0, 0x1003F);     $Check1 >>= 2;       $Check1 = (($Check1 >> 4) & 0x3FFFFC0 ) | ($Check1 & 0x3F);     $Check1 = (($Check1 >> 4) & 0x3FFC00 ) | ($Check1 & 0x3FF);     $Check1 = (($Check1 >> 4) & 0x3C000 ) | ($Check1 & 0x3FFF);     $T1 = (((($Check1 & 0x3C0) << 4) | ($Check1 & 0x3C)) <<2 ) | ($Check2 & 0xF0F );     $T2 = (((($Check1 & 0xFFFFC000) << 4) | ($Check1 & 0x3C00)) << 0xA) | ($Check2 & 0xF0F0000 );     return ($T1 | $T2); } function CheckHash($Hashnum) {     $CheckByte = 0;     $Flag = 0;     $HashStr = sprintf('%u', $Hashnum) ;     $length = strlen($HashStr);     for ($i = $length - 1;  $i >= 0;  $i --) {         $Re = $HashStr{$i};         if (1 === ($Flag % 2)) {                           $Re += $Re;                 $Re = (int)($Re / 10) + ($Re % 10);         }         $CheckByte += $Re;         $Flag ++;       }     $CheckByte %= 10;     if (0 !== $CheckByte) {         $CheckByte = 10 - $CheckByte;         if (1 === ($Flag % 2) ) {             if (1 === ($CheckByte % 2)) {                 $CheckByte += 9;             }             $CheckByte >>= 1;         }     }     return '7'.$CheckByte.$HashStr; } function getPageRank($url) {         $agents = array(                     'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30',                     'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.9',                     'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.8',                 );     $useragent = @ini_get('user_agent');     @ini_set('user_agent', $agents[array_rand($agents)]);     $ch = CheckHash(HashURL($url));     $pr_url ="http://toolbarqueries.google.com/search?client=navclient-auto&ch=$ch&features=Rank&q=info:$url";          $data = file_get_contents($pr_url);     @ini_set('user_agent', $useragent);     $pos = strpos($data, "Rank_");     if($pos !== false)     {         $pr = trim(substr($data, $pos + 9));         return str_replace("\n",'',$pr);     }     else         return 0; } ?>
