title: EBS payment gateway integration using PHP
body: <p>i need to integrate ebs payment gateway. i am searching lot but i could find the solution. 
  Response is provided using POST method to the URL defined under ReturnURL parameter in the payment request. <code>$response['ResponseCode'] == 0</code> means transaction successfully completed. Other than 0 value transactions failed. I can't find <code>$response['ResponseCode'] == 0</code>.</p>
  
  <p>here my code</p>
  
  <pre><code>if(isset($_GET['DR'])) {
   require('Rc43.php');
   $DR = preg_replace("/\s/","+",$_GET['DR']);
  
   $rc4 = new Crypt_RC4($secret_key);
   $QueryString = base64_decode($DR);
   $rc4-&gt;decrypt($QueryString);
   $QueryString = split('&amp;',$QueryString);
  
   $response = array();
   foreach($QueryString as $param){
      $param = split('=',$param);
      $response[$param[0]] = urldecode($param[1]);
   }
  }
  </code></pre>
