array_walk callback not working [duplicate]

Question

I have PeopleSearch class that has all static method instead of one method. Whne i call this function then i receive exceptio that is below

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

Below is my working code

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; } }

Change 'setUserRequestStatus' with [$this, 'setUserRequestStatus'] — splash58

As per the manual please replace your code with the below one

array_walk($userArray, array('self', 'setUserRequestStatus'));

Hope this helps

Your callback function is static so you may use the below code snippet array_walk($array, array('self', 'walkFunction'));
