Question

我有PeopleSearch类，它具有所有静态方法而不是一个方法。当我打电话给这个功能时，我会收到低于

的例外情况

array_walk() expects parameter 2 to be a valid callback, function 'setUserRequestStatus' not found or invalid function name

以下是我的工作代码

class PeopleSearch {

        public static function searchPeople($client = null) {
             $inputs = Request::get('data');
             $data['User'] = [];
             $result = $client->search(self::prepare_search_params_people($inputs));
             if (!empty($result) && count($result['hits']['hits']) > 0) {
                  $userArray = array_column($result['hits']['hits'], '_source');
                  // check user friend requests
                  $requestSents = FriendRequest::get_friend_requests($inputs['User']['id'], array_column(array_column($result['hits']['hits'], '_source'), 'id'))->toArray();
                 array_walk($userArray,'setUserRequestStatus',array_column($requestSents, 'request_to'));
                 echo "<pre>";
                 print_r($userArray);
                 exit;
             }
       }

      public function setUserRequestStatus($user, $key, $requests_sent_to) {
            $user['request_sent'] = in_array($user['id'], $requests_sent_to) ? true : false;
      }
    }

根据手册，请用下面的代码替换您的代码

array_walk（$ userArray，array（＆＃39; self＆＃39;，＆＃39; setUserRequestStatus＆＃39;））;

希望这有帮助

array_walk回调无法正常工作
