I used it once for changing all my sitelinks once. IMHO it is simpler to do
function walk_tree($root) {
mgd_get_topic($root);
<- do something to root ->
if ($this = mgd_list_(pages|topics)($root->id) while ($this->fetch()) {
walk_tree($this->id);
}
}
I find that more easy to understand in my head. It does the samething though.
