How to get the family id's of a Wordpress page

/ Published in: PHP

This small snippet can be used to get the children and grand children of a Wordpress page. See the comments for how it works

/*
  $grandma = the ancestor to check it with
  $include can be used to include grandma herself too
  please pay attention that the GetChildren is calling itself
  recursively
  use it like: $family = $this->GetFamilyTree($id, true) or
  $family = $this->GetFamilyTree($id, false) when you don't want
  grandma herself too
  see: http://codex.wordpress.org/Function_Reference/get_children

    if ($include) {
        array_push($this->family, $grandma);
