PHP Code to get google pagerank?

Anybody know of code for me to get the pagerank from google?

Thanks

 

i recently used this code, as seen here http://www.stucknut.com/pagerank/

I couldnt get it to work from shared hosting, so I used a server here at my house.

<?php  
define('GOOGLE_MAGIC', 0xE6359A60);  
class pageRank{ 
var $pr;  
function zeroFill($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; $a ^= ($this->zeroFill($c,13)); 
   $b -= $c; $b -= $a; $b ^= ($a<<8); 
   $c -= $a; $c -= $b; $c ^= ($this->zeroFill($b,13)); 
   $a -= $b; $a -= $c; $a ^= ($this->zeroFill($c,12)); 
   $b -= $c; $b -= $a; $b ^= ($a<<16); 
   $c -= $a; $c -= $b; $c ^= ($this->zeroFill($b,5)); 
   $a -= $b; $a -= $c; $a ^= ($this->zeroFill($c,3)); 
   $b -= $c; $b -= $a; $b ^= ($a<<10); 
   $c -= $a; $c -= $b; $c ^= ($this->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 = $this->mix($a,$b,$c); 
   $a = $mix[0]; $b = $mix[1]; $c = $mix[2]; 
   $k += 12; 
   $len -= 12;  
  } 
  $c += $length; 
  switch($len){  
   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]);  
  }  
  $mix = $this->mix($a,$b,$c);  
/* report the result */  
return $mix[2];  
}  



function strord($string) {  
  for($i=0;$i<strlen($string);$i++) {  
   $result[$i] = ord($string{$i});  
  }  
return $result;  
}  

function printrank($url){ 
  $ch = "6".$this->GoogleCH($this->strord("info:" . $url));  
   
  $fp = fsockopen("www.google.com", 80, $errno, $errstr, 30); 
  if (!$fp) { 
     echo "$errstr ($errno)<br />\n"; 
  } else { 
     $out = "GET /search?client=navclient-auto&ch=" . $ch .  "&features=Rank&q=info:" . $url . " HTTP/1.1\r\n"; 
     $out .= "Host: www.google.com\r\n"; 
     $out .= "Connection: Close\r\n\r\n";  
     fwrite($fp, $out); 
     while (!feof($fp)) { 
       $data = fgets($fp, 128); 
       $pos = strpos($data, "Rank_"); 
         if($pos === false){ 
         }else{ 
           $pagerank = substr($data, $pos + 9); 
           $this->pr_image($pagerank); 
         } 
     } 
     fclose($fp);  
  } 
}

Thanks, I'll give it a shot

 

I have and have tried a working PHP Pagerank script, but can somebody explain, how these scripts extract the information from Google servers???

 

it all starts with this line:
$fp = fsockopen("www.google.com", 80, $errno, $errstr, 30);

 

Am talking about the $ch

 

for some reason this script is not working for me, blank screen, any ideas?

 

if you are going through a server hosting company, chances are that they block that sock or whatever it is to get the data.

i put the same script on a server i have at my house and it worked fine.

 

bah, fsockopen sucks! You should replace that routine with a cUrl routine. You can check 1000 domains with cUrl in the time it takes to check 100 with fsockopen. (no test bench done, but I have used fsockopen vs cUrl and cUrl kicked fsockopen butt in the software I have).

 

Is there any screen shot available for the installed script?

 

the script writes <img> code with a link to a generic PR image, which you have to either create or make yourself.

i made my own, with a sports theme, as seen in my sig link

 

thank you......

 

That script make me a 500 - Internal Sever Error.

 

On my webhosting, this script generates wrong $ch and I get only 403 Forbidden :-/

 

hmm, thats strange.

the hosting companies still must be restricting some things.
still works fine for me.

 

I have one try it at http://www.detectpr.com

WOrks best entering 30 or less domains, more takes a little longer

and it only returns domains with pr1 or higher.

If interested pm me my price includes setup
