在PHP（Laravel）中访问数组内的嵌套对象

Question

我为如何访问嵌套对象而苦苦挣扎。

    $dt = Carbon::parse($year.'-'.$month.'-1');
    $godziny = array();
    $gs = $lekarz->od;
    $gz = $lekarz->do;
    $ile = $gz-$gs;
    for($j=0; $j<4*$ile; $j++){
        if($j%4==0){
            $wm = "00";
        }
        else{
            $wm = ($j%4)*15;
        }
        if($gs+floor(($j/4)) < 10){
            $dz="0".$dz = $gs+floor(($j/4));
        } else{
            $dz = $gs+floor(($j/4));
        }
        $godziny[$j]['godzina'] = $dz;
        $godziny[$j]['minuty'] = $wm;
        if(!empty(Kolejka::where('data', 'LIKE', $year.'-'.$month.'-'.$day.' '.$dz.':'.$wm.'%')->get())){
            $godziny[$j]['odbyta'] = Kolejka::where('data', 'LIKE', $year.'-'.$month.'-'.$day.' '.$dz.':'.$wm.'%')->get();
            dd(get_object_vars($godziny[$j]['odbyta']));
           // $godziny[$j]['pacjent'] = Pacjent::where('id', '=', $godziny[$j]['odbyta']->{0}->pacjent_id);
        } else { 
            $godziny[$j]['odbyta'] = '';
        }
    }

除最后一部分外，一切正常。似乎我尝试以任何方式访问这些数据（通过使用 $godziny[$j]['odbyta']['pacjent_id'] 或通过 $godziny[$j]['odbyta']->pacjent_id）它刚刚赢了不行。我真的不知道该怎么办。

这是我的 [$j]['odbyta] 数据：

{
    "id": 1,
    "pacjent_id": "13",
    "lekarz_id": "1",
    "data": "2017-04-05 10:15:00",
    "odbyta": "0",
    "created_at": "2017-04-05 16:14:42",
    "updated_at": "2017-04-05 16:14:42"
}

即生成具有模式的数据的代码： $j 的最大数量是 36

$godziny[0]['godzina'] = $dz //That's for setting hour to array
$godziny[0]['godzina'] = $wm; //That's for assigning minutes
$godziny[0]['odbyta'] <- that's of value of object that i listed above

我怎样才能访问这个对象的数据？ 所以 $godziny[0]['odbyta'] 可以给我它包含的对象的值吗？

Answer 1

你不能只使用 Model->where...first() 吗？而不是作为对象访问它：

$godziny[$j]['odbyta'] = Kolejka::where('data', 'LIKE', $year.'-'.$month.'-'.$day.' '.$dz.':'.$wm.'%')->first();
$godziny[$j]['pacjent'] = Pacjent::where('id', '=', $godziny[$j]['odbyta']->pacjent_id);
