[amaelftah]

this PR will allows eloquent collection find() method to accept collection

$users = User::get()->find(collect([20,40,30]))

Maybe it will be better to check for Arrayable contract?

if ($key instanceof \Illuminate\Contracts\Support\Arrayable) {
    $key = $key->toArray();
}

@Te7a-Houdini Do you have a use case better than collect([1, 2, 3])?

You are duplicating and complicating some unnecessary work 😅

@carusogabriel

$collection = collect();

// Complicated logic

$users = User::get()->find($collection);
