Whole day I have been working on this trouble but could not find needed information. Okay, I need adding new fields in the ACF group by PHP. I tested function acf_add_local_field. Nothing working. I see that function go to $store->set( $key, $field )->alias( $key, $name );. And everything should be okay but fields not add. Please, help me. How I can add new ACF fields by PHP? Only fields without group. I have needed group.

                                array(
                                    'key'   => "generalInfo_".$value,
                                    'label' => $value, 
                                    'name' => "generalInfo_".$value, 
                                    'type' => 'text', 
                                    'parent' => 'generalInfo', 
                                    'parent_layout' => 'group_6187fed087950',
                                    'instructions' => '',
