"package_detail": [
                {
                    "id": 229,
                    "package_id": 66,
                    "data_scoin_id": 210,
                    "unit_scoin_id": 3,
                    "created_at": "2020-01-16 21:51:18",
                    "updated_at": null,
                    "created_by": 1,
                    "updated_by": null,
                    "unit_scoin": {
                        "id": 3,
                        "unit_scoin": 1000,
                        "code_scoin": "SCOINAKHDLL2019                                                                                                                                                                                                                                                ",
                        "description": "Seribu Scoin",
                        "rate_exchange": "Rp. 1.000",
                        "created_at": "2019-09-07 10:52:47",
                        "updated_at": null,
                        "created_by": null,
                        "updated_by": null
                    }
                },

I want to overwrite unit_scoin (parent) with unit_scoin (child) I've been try to map and each the the package_detail index like this : 

$packages = ScoinPackage::with('package_detail.unit_scoin')->get()
        ->map(function($d){
            $d->package_detail->each(function($dd) use (&$arr){
                $dd->unit_scoin = $dd->unit_scoin->unit_scoin;
            });

            return $d;
        });

But it was doesn't work, anyone can help me out ?

conflict cause the object name is same.So first, save in a variable and unset it

$packages = ScoinPackage::with('package_detail.unit_scoin')->get()->map(function($d){
            $d->package_detail->map(function($dd){
                $unit = $dd->unit_scoin;
                unset($dd->unit_scoin); 
                $dd->unit_scoin = $unit->unit_scoin;
                return $dd;
            });
            return $d;
        });

You need to use transform() method, since each() just iterates over the collection without changing and map() one creates and returns new collection object (and doesn't modify initial one).

Something like this should do a trick:

$packages = ScoinPackage::with('package_detail.unit_scoin')->get()
    ->map(function($d){
        $d->package_detail->transform(function ($dd) {
            return $dd->unit_scoin = $dd->unit_scoin->unit_scoin;
        });

        return $d;
    });

You need to use the map() function to loop over the package_details as well. The each function won't return or change anything unless you pass the value by reference.

$packages = ScoinPackage::with('package_detail.unit_scoin')->get()
    ->map(function($d){
        $d->package_detail->map(function($dd) use (&$arr){
            $dd->unit_scoin = $dd->unit_scoin->unit_scoin;

            return $dd;
        });

        return $d;
    });
