i writing restful web service in symfony2. same service working fine on localhost returning response data not on server. print_r() response variable , showing data array.

    $user = new users();          $user->setusername($paramfetcher->get('email'));         $password = $paramfetcher->get('password');         $user->setusertype('business');         if($password==""){              $user->setpassword(rand(0,1000));          }else{              $user->setpassword($password);         }      $data['userdetails']['id'] = $user->getid();     $data['userdetails']['username'] = $user->getusername();     $data['userdetails']['password'] = $user->getpassword();     $data['userdetails']['usertype'] = $user->getusertype();       $em->persist($user);         $em->flush();         //print_r($data); print_r($buss);      $response[]=array("code"=>200,"message"=>"success","data"=>$data); 

please guide

if code inside controller function need return response. if want output json need return jsonresponse object:

return new \symfony\component\httpfoundation\jsonresponse($response);
