Why not try searching online for one or try writing you're own and asking for help after you show what you have started?

Stop expecting to be spoon fed on everything!

Save this code pagerank.class.php

PHP Code:

<?php
class GooglePageRankChecker {
 
  // Track the instance
  private static $instance;
 
  // Constructor
  function getRank($page) {
    // Create the instance, if one isn't created yet
    if(!isset(self::$instance)) {
      self::$instance = new self();
    }
    // Return the result
    return self::$instance->check($page);
  }
 
  // Convert string to a number
  function stringToNumber($string,$check,$magic) {

      }
      return $check;

  // Create a url hash
  function createHash($string) {

      return ($calc1 | $calc2);
  }
 
  // Create checksum for hash
  function checkHash($hashNumber)
  {
      $check = 0;
    $flag = 0;

        }

      }
    }
 
    return '7'.$check.$hashString;

      // Close the connection
      fclose($socket);
 
      // Return the rank!
      return $result;
    }
  }
}
?>

Save this code as index.php

PHP Code:

<?php
if (isset($_REQUEST['domain'])) {
    include('pagerank.class.php');
    $domain = str_replace('http://', '', trim($_REQUEST['domain']));
    $check = new GooglePageRankChecker;
    $pr = $check -> getRank($domain);
    $result = '<div align="center"><h2>' . $domain . ' has pagerank: ';
    $result .= $pr;
    $result .= '</h2></div>';
    $title =  $domain . ' has pagerank: '.$pr .' |Page Rank Checker';
}
else
{
    $title = 'Page Rank Checker';
}
?>

LMFAO!!! Come on Ivan try and teach yourself something for once. Instead of being so lazy you just ask here and then sit and wait for someone with a spoon to feed you the answers.

@Ivan create a folder and name it whatever you like for instance "PageRank-Checker" add those files into this folder then unload this folder to your server root directory. Then to access it just type "yourdomain.com/PageRank-Checker"
