          ]

Я могу использовать цикл foreach для получения значений определенного отеля, как показано ниже, код, 

//All the hotel names
@foreach ($array['Hotels']['Hotel'] as $key => $hotel){

echo $hotel['HotelName']; //Displays all the hotel names
}

// All the RoomTypes of a single hotel array
@foreach ($hotel['RoomTypeDetails']['Rooms']['Room'] as $k => $rt {

  echo $rt['RoomType'];  //Displays all the RoomTypes of a hotel
}

//I would like to get the discounts of a single room type of a hotel
@foreach ($rt['DiscountDetails'] as $d { 

  echo $d['DiscountName'] // NOT WORKING - Throws error, Undefined index - 
  NEED HELP HERE
}

//I would like to get the supplements of a single room type of a hotel
@foreach ($rt['SupplementDetails']['Supplement'] as $s { 

  echo $s['Name'] // NOT WORKING - Throws error, Undefined Index - NEED HELP  
  HERE
}

Я занимаюсь разработкой с использованием инфраструктуры laravel, v5.7, эти данные представляют собой XML-ответы через удаленный API, декодированные json для использования в моем приложении. Я пытался выяснить, как отобразить более глубокие вложенные элементы массивов внутри многомерного массива.

Я хотел бы получить следующую иерархию значений из вышеприведенных выходных данных json.

  1. Отель> Номер> Цены (скидки)
  2. Отель> Номер> Доплата

Я искал переполнение стека и другие форумы, и я нашел некоторые сценарии и возможные решения, также применил некоторые, но, похоже, он не отображает значения, которые мне нужны.

Пробовал вложенные для каждой функции, но я не мог заставить ее работать. Если у вас, ребята, есть какой-либо опыт работы с такими данными, пожалуйста, помогите мне или направьте меня за рекомендациями по работе с более глубокими вложенными многомерными массивами.

Если вам интересно, здесь дамп для переменной $ rt [она уже находится в одном элементе отеля]

насколько я вижу, вы забыли некоторые части своего кода, индексы 

@foreach ($rt['RoomTypeDetails']['Rooms']['Room']['DiscountDetails'] as $d { 

  echo $d['DiscountName'];
}


@foreach ($rt['RoomTypeDetails']['Rooms']['Room']['SupplementDetails']['Supplement'] as $s { 

  echo $s['Name'];
}

Вы можете использовать вспомогательную функцию Laravel, например, data_get (), даже функции коллекций, такие как get(), pluck() и т. Д., Для работы с Arrayable Items.

Давайте используем data_get() в качестве примера, чтобы получить все MealPlan, используя этот путь RoomTypeDetails->Rooms->Room->*-> MealPlan: 

$data = [
            "HotelName" => "AL MANZIL DOWNTOWN DUBAI",

            ]
        ];

        return data_get($data,'RoomTypeDetails.Rooms.Room.*.MealPlan');

Это даст вам: 

[
"ROOM ONLY",
"BED AND BREAKFAST"
]

Обновление:

Подобно тому, как @simonecosci упоминал, чтобы получить индивидуальное значение, используя нотацию «точка», вы можете использовать array_get , чтобы у вас было: 

array_get($data,'RoomTypeDetails.Rooms.Room.1.MealPlan')

Преимущество использования этого метода помимо исключения foreach состоит в том, что он возвращает null, когда свойство / индекс не существует в массиве.

Попробуй это. Получение некоторого значения не требует цикла. 

//All the hotel names
@foreach ($array['Hotels']['Hotel'] as $key => $hotel){

    echo $hotel['HotelName']; //Displays all the hotel names

    // All the RoomTypes of a single hotel array
    @foreach ($hotel['RoomTypeDetails']['Rooms']['Room'] as $k => $rt {

      echo $rt['RoomType'];  //Displays all the RoomTypes of a hotel


      //I would like to get the discounts of a single room type of a hotel
      if(isset($rt['DiscountDetails']['Discount']['DiscountName']))
          echo $rt['DiscountDetails']['Discount']['DiscountName'];
      else
          echo 'No discount';

      //I would like to get the supplements of a single room type of a hotel
      if(isset($rt['SupplementDetails']['Supplement']['Name']))
          echo $rt['SupplementDetails']['Supplement']['Name'];
      else
          echo 'No Supplement';

    }
}
...
