How to display the number of likes of the top user of the VK group?

Question

PHP

The script displays the user who, with the largest number of likes, put on the group wall (name, surname, avatar are displayed)

public function getLikerId()
    {
        global $config;

        $users = [];

        $time_to = time();
        if (!empty($config['like_interval']['to'])) {
            $time_to = strtotime($time_to);
        }

        $posts = $this->getPosts(-$config['group_id']);

        foreach ($posts as $post) {
            if ($post->date < strtotime($config['like_interval']['from']) || $post->date > $time_to) {
                continue;
            }

            $likes = $this->getLikes(-$config['group_id'], $post->id);

            foreach ($likes->users as $id) {
                if (isset($users[$id])) {
                    $users[$id]++;
                } else {
                    $users[$id] = 1;
                }
            }
        }

        arsort($users);
        $user_ids = array_keys($users);
        $user_id = array_shift($user_ids);
        return $user_id;
    }
 
    private function getLikes($owner_id = 1, $item_id = 1, $type = 'post')
    {
        return $this->api('likes.getList', [
            'owner_id' => $owner_id,
            'item_id'   => $item_id,
            'type'   => $type,
            ]);
    }

how to get the number of these likes, how much he put?

Answer 1

1. Go through all posts using the wall.get method - Bad .
2. Using the CallBack API , receive notifications about likes set by the user and save them on your server (preferably in a database) - Good.
