Hi I gave my REST application a commentary function and I am not sure if my code couldn’t be more effective? I am happy if anybody sees something to improve 
This Code produces an output that gives 2 tiers of comments 10 in the first tier and 2 if there is a second tier. If there are more tiers or more comments on tier 2 the REST Route is called again at this position to populate the DOM.
The discussContent comes from an noSQL DB and is controlled by an SQL with the Table Discuss.
I call the table Discuss 3 times with different query operations.Each powered by an foreach with different input, so is it smart that way?
private function findDiscussDiscussion($id, $offset)
{
$table = Discuss::find()
->where([
'refer_id' => $id,
'refer_type' => 'discussion'
])
->with('discussContent')
->orderBy(('discuss.id ASC'))
->limit(10)
->offset($offset)
->all();
foreach ($table as $item) {
$tier1_table = Discuss::find()
->where([
'refer_id' => $item['id'],
'refer_type' => 'discussion'
])
->with('discussContent')
->limit(2)
->offset(0)
->all();
if (isset($tier1_table)) {
foreach ($tier1_table as $tier1_item) {
$tier2_table = Discuss::find()
->where([
'refer_id' => $tier1_item['id'],
'refer_type' => 'discussion'
])
->count();
$discussion[] = array(
'id' => $tier1_item['id'],
'title' => $tier1_item->discussContent['title'],
'content' => $tier1_item->discussContent['content'],
'author' => $tier1_item->discussContent['author'],
'tags' => $tier1_item->discussContent['tags'],
'mentions' => $tier1_item->discussContent['mentions'],
'refer' => $tier1_item->discussContent['refer'],
'discussion' => $tier2_table
);
}
} else { $discussion = 0; }
$result[] = array(
'id' => $item['id'],
'title' => $item->discussContent['title'],
'content' => $item->discussContent['content'],
'author' => $item->discussContent['author'],
'tags' => $item->discussContent['tags'],
'mentions' => $item->discussContent['mentions'],
'refer' => $item->discussContent['refer'],
'discussion' => $discussion
);
}
return isset($result) ? $result : null;
}
