hello guys i am trying to get google page rank for the sites. i guess i need google Checksum code. i have looked everywhere and searched on google but all of the codes i found didnt work.

 

this is one of the code i found

 

<?php
/*
  This code is released unto the public domain
*/
header("Content-Type: text/plain; charset=utf-8");
define('GOOGLE_MAGIC', 0xE6359A60);

//unsigned shift right
function zeroFill($a, $b)
{
  $z = hexdec(80000000);
      if ($z & $a)
      {
          $a = ($a>>1);
          $a &= (~$z);
          $a |= 0x40000000;
          $a = ($a>>($b-1));
      }
      else
      {
          $a = ($a>>$b);
      }
      return $a;
}

function mix($a,$b,$c) {
$a -= $b; $a -= $c; $a ^= (zeroFill($c,13));
$b -= $c; $b -= $a; $b ^= ($a<<8);
$c -= $a; $c -= $b; $c ^= (zeroFill($b,13));
$a -= $b; $a -= $c; $a ^= (zeroFill($c,12));
$b -= $c; $b -= $a; $b ^= ($a<<16);
$c -= $a; $c -= $b; $c ^= (zeroFill($b,5));
$a -= $b; $a -= $c; $a ^= (zeroFill($c,3));
$b -= $c; $b -= $a; $b ^= ($a<<10);
$c -= $a; $c -= $b; $c ^= (zeroFill($b,15));

return array($a,$b,$c);
}

function GoogleCH($url, $length=null, $init=GOOGLE_MAGIC) {
  if(is_null($length)) {
      $length = sizeof($url);
  }
  $a = $b = 0x9E3779B9;
  $c = $init;
  $k = 0;
  $len = $length;
  while($len >= 12) {
      $a += ($url[$k+0] +($url[$k+1]<<8) +($url[$k+2]<<16)
+($url[$k+3]<<24));
      $b += ($url[$k+4] +($url[$k+5]<<8) +($url[$k+6]<<16)
+($url[$k+7]<<24));
      $c += ($url[$k+8] +($url[$k+9]<<8)
+($url[$k+10]<<16)+($url[$k+11]<<24));
      $mix = mix($a,$b,$c);
      $a = $mix[0]; $b = $mix[1]; $c = $mix[2];
      $k += 12;
      $len -= 12;
  }

  $c += $length;
  switch($len)              /* all the case statements fall through */
  {
      case 11: $c+=($url[$k+10]<<24);
      case 10: $c+=($url[$k+9]<<16);
      case 9 : $c+=($url[$k+8]<<8);
        /* the first byte of c is reserved for the length */
      case 8 : $b+=($url[$k+7]<<24);
      case 7 : $b+=($url[$k+6]<<16);
      case 6 : $b+=($url[$k+5]<<8);
      case 5 : $b+=($url[$k+4]);
      case 4 : $a+=($url[$k+3]<<24);
      case 3 : $a+=($url[$k+2]<<16);
      case 2 : $a+=($url[$k+1]<<8);
      case 1 : $a+=($url[$k+0]);
       /* case 0: nothing left to add */
  }
  $mix = mix($a,$b,$c);
  /*-------------------------------------------- report the result */
  return $mix[2];
}

//converts a string into an array of integers containing the numeric
value of the char
function strord($string) {
  for($i=0;$i<strlen($string);$i++) {
      $result[$i] = ord($string{$i});
  }
  return $result;
}
// [url]http://www.example.com/[/url] - Checksum: 6540747202
$url = 'info:'.$_GET['url'];
print("url:\t{$_GET['url']}\n");
$ch = GoogleCH(strord($url));
printf("ch:\t6%u\n",$ch);
?>

 

any help is greatly appreciated

 

thankyou

This is what I use on my directories:

           $a &= (~$z);
           $a |= 0x40000000;
           $a = ($a>>($b-1));
       }
       else
       {
           $a = ($a>>$b);

       return $a;

        /* case 0: nothing left to add */
   }
   $mix = mix($a,$b,$c);
   /*-------------------------------------------- report the result */
   return $mix[2];
}

//converts a string into an array of integers containing the numeric value of the char
function strord($string) {
   for($i=0;$i<strlen($string);$i++) {
       $result[$i] = ord($string{$i});
   }
   return $result;
}

function getrank($url) {
$url = 'info:'.$url;
$ch = GoogleCH(strord($url));

$file = "http://www.google.com/search?client=navclient-auto&ch=6$ch&features=Rank&q=$url";
$data = file($file);

$rankarray = explode (':', $data[2]);
$rank = (int)$rankarray[2];
return $rank;
}

function getpr($url){
$rank = (int)getrank($url);
$str = '<img src="/directory/images/pos.gif" height="4px" width="'.($rank*5).'" align="middle" alt="PageRank '.$rank.'" title="PageRank '.$rank.'"><img src="/directory/images/neg.gif" height="4px" width="'.(50-$rank*5).'" align="middle" alt="PageRank '.$rank.'" title="PageRank '.$rank.'">';
return $str;
}

?>

Include the file somewhere and then call the getpr() function.

 

$prbar = getpr("http://www.oscommerce.com/");

 

The $prbar string now has the familiar PR bar for osC. Be sure to download the pos.gif and neg.gif as well.

 

It's handy since you don't have to call it as a page parameter. You can pump through as many URLs as you need with the conveience of a function :)
