Laravel Array or Object? - php

Question

i'm kinda new with Laravel Framework. And now confused with data type like array and object. I got a data like this :
"data[0].detailItem" => array:2 [
0 => array:3 [
"itemNo" => "100011"
"unitPrice" => 0
"quantity" => 6
]
1 => array:3 [
"itemNo" => "102972"
"unitPrice" => 0
"quantity" => 3
]
]
is there a way I change it into :
"data[0].detailItem" => [
{
"itemNo" => "100011"
"unitPrice" => 0
"quantity" => 6
},
{
"itemNo" => "102972"
"unitPrice" => 0
"quantity" => 3
}
]
Edit :
Heres the code
public function apiStore(Request $request){
$detailReceiveItem = DB::table('t_receive_item_detail')->where('receive_item_id','=',$request->idReceiveItem)->get();
$detailItem = [];
foreach($detailReceiveItem as $key=>$receiveItem){
$temp = [
'itemNo' => $receiveItem->item_code,
'unitPrice' => 0,
'quantity' => $receiveItem->qty,
];
array_push($detailItem,$temp);
}
$input = [
'data[0].vendorNo' => $request->vendorNo,
'data[0].receiveNumber' => $request->receiveNumber,
'data[0].transDate' => date('d/m/Y',strtotime($request->transDate)),
'data[0].detailItem' => (object)$detailItem
];
$insertReceiveItem = Http::withHeaders([
'Authorization' => 'Bearer '.session()->get('access_token'),
'X-Session-ID' => session()->get('X-Session-ID'),
])->asForm()->post(session()->get('host').'api url here',$input);
return response()->json(['status'=>1, 'url'=>'/api-accurate/receive-item','message'=>'Receive Item Created Successfully!']);
}
That's my code. I need to convert $detailItem into a object.
