This data was retrieved via eloquent model, like this:
$ad_groups = Ad_user::find($request->decodedToken->user_id)->ad_groups()->get();
I don't know if any "inherited" functionality of eloquent model still resides within $ad_groups, thats why Im posting it here for you so you know what we have to work with ^^
What I basically want to accomplish is to get the ids extraced. I could of course just write a foreach loop. But I'm new to Lumen/Laravel and I'd like to know whether there is also some awesome method like ...>getMeWhatIWant() available in this context or not :D
You can use the pluck method on a Laravel collection (official docs here).
You just have to pass the column name that you want to retrieve as first parameter:
$ids = $ad_groups->pluck('id');
dd($ids);
