$feedbacks is a array , you can't call orderBy() on a array .

Call to a member function orderBy() on a non-object
I'm trying to order my selected feedbacks by latest first and only showing 5 but when trying to achieve this, I get the error mentioned in the title.
It's prob simply something ridiculous or stupid that i'm missing but what am I doing wrong?
This is my code:
public function index(Tnb $tnb)
{
$user = Auth::user();
$feedbacks = array();
foreach($user->tnbs as $tnb)
{
foreach($tnb->feedbacks as $feedback)
{
$feedbacks[] = $feedback;
}
}
dd($feedbacks->orderBy('created_at', 'DESC'));
return view('profile.index', compact('user', 'tnb', 'feedbacks'));
}

@tangoG Could you explain how I could fetch the latest 5 feedbacks out of the array, if possible? Thanks

usort($feedbacks, function ($a, $b) { return $a->created_at - $b->created_at; });
$last_5_feedbacks = array_slice ($feedbacks, -5);

You can try with collection :
collect($feedbacks)->sortByDesc('created_at')->take(5)

Convert array to collection:
$feedbacks = ['a', 'b', 'c', null];
$collection = collect($feedbacks)->map(function($name)
{
return strtoupper($name);
})
->reject(function($name)
{
return empty($name);
});
