生产模式下的推送通知未到来但在开发中它即将到来

My PNS is working good in development mode. I have done this using raywendelich blog. same way i have created certificates in production mode and run same script from server but not receiving any notification.

Which additional step needed when we are testing in production mode from our server.Its very urgent need. plase help what to do for production mode.

our PHP code

<?php

// Put your device token here (without spaces):
$deviceToken = 'd5d89cab86e6f1a3cfa66dd853f3f4d7dd932c4a6da793cb9c86d31e9cfcb31f';

// Put your private key's passphrase here:
$passphrase = '*******';

// Put your alert message here:
$message = '****';

 $ctx = stream_context_create();
 stream_context_set_option($ctx, 'ssl', 'local_cert', 'ckm.pem');
 stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);

 // Open a connection to the APNS server
 $fp = stream_socket_client(
'ssl://gateway.push.apple.com:2195', $err,
$errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);

 if (!$fp)
exit("Failed to connect: $err $errstr" . PHP_EOL);

echo 'Connected to APNS' . PHP_EOL;

// Create the payload body
$body['aps'] = array(
'alert' => $message,
'sound' => 'default'
);

  // Encode the payload as JSON
 $payload = json_encode($body);

 // Build the binary notification
 $msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload))   . $payload;

 // Send it to the server
 $result = fwrite($fp, $msg, strlen($msg));

 if (!$result)
echo 'Message not delivered' . PHP_EOL;
 else
echo 'Message successfully delivered' . PHP_EOL;

  // Close the connection to the server
  fclose($fp);
