                           $strFromNumber,
                           $strToNumber,
                           $strMsg
                          );     
                  $result->content = $strMsg;
                  $result->success = true;
                  return $result;
                        }
                                                }
      ?>

above code sends SMS perfect but does not work on a live project when deployed on IIS server on windows server. I have seen few posts relevant to this problem but most have suggested to allow curl on the server. If so please tell how to enable curl on IIS server

Problem was in SSL certificate over IIS server. just open TinyHttp.php in twilio lib: add CURLOPT_SSL_VERIFYPEER => FALSE, at $opts array
