How to find all comments in a VK group?

Question

PHP

Hey! I want to purge comments like on Real Lentach , but I don’t know how to pull comments from under all posts at once. I looked in the documentation - I couldn’t find it, maybe I’m just looking in the wrong place.
I would be glad if someone has a solution to this problem, or at least a hint on where to look.
(PHP started to study recently, so special thanks for the comments on the code).
Thanks in advance! :)

1. Connect the callback API , and receive notifications on your server about each comment.
   For small groups, you can
   without callback API

   1. Вы знаете / запоминаете где-то ID всех своих постов.
      
   2. Через wall.getComments() получаете для каждого поста список комментов с отметкой времени и счётчиком лайков.
      
   3. Комменты старше X и числом лайков меньше Y – удаляете.
