Добавление массива в другой массив (не array_push или array_merge)

Я новичок в PHP, и у меня есть некоторые проблемы с переносом массивов в другой. Для более подробной информации, я хочу показать часть моего кода:

Это пример ответа:

редактировать: у меня есть более одного "ать предложение " 

{
  "data": [

            ]
          }
        }
      ]
    },
    {
      "sentenceArray": [

              },
              {

          }
        },
        {
          "path": {
            "type": "bus",
            "nodes": [
              {
                "lat": 39.952418,
                "lng": 32.85727
              },
              {
                "lat": 39.952797,
                "lng": 32.856825
              },
              {
                "lat": 39.953102,
                "lng": 32.856438
              }
            ]
          }
        },
        {
          "path": {
            "type": "bus",
            "nodes": [
              {
                "lat": 39.964951,
                "lng": 32.841305
              },
              {
                "lat": 39.964785,
                "lng": 32.841514
              }
            ]
          }
        }
      ]
    }
  ]
}

Вот что я сделал до сих пор: 

for($j = 0; $j < $l; $j++) {
        if($sentenceArray[$j]['path']['type'] == "bus") {
            if(isset($sentenceArray[$j]['path']['nodes'])){
                $busCount++;
                $nodes = $sentenceArray[$j]['path']['nodes'];
                for($k = 0, $c = count($nodes); $k < $c; $k++) {
                    $latlng = $nodes[$k];
                    array_push($arrBus,$latlng);
                }

            }
        }
    }

Сначала я пытался поместить массивы в один массив, но мой код объединил все это в один массив, а не два отдельных массива в одном массиве. Между прочим, реальные данные намного больше этого и генерируются динамически. Таким образом, количество шинных массивов может быть два или более. Это немного сбивает с толку меня, как начинающего разработчика PHP.

Позвольте мне показать вам, какова моя цель здесь: 

var lineCoordinates = {
  "0": [
    {
                                "lat": 39.952418,
                                "lng": 32.85727
                            },
                            {
                                "lat": 39.952797,
                                "lng": 32.856825
                            },
                            {
                                "lat": 39.953102,
                                "lng": 32.856438
                            }
  ],
  "1": [
    {
                                "lat": 39.964951,
                                "lng": 32.841305
                            },
                            {
                                "lat": 39.964785,
                                "lng": 32.841514
                            }
                            
                           
  ]
}

Этот пример вывода будет работать для меня хорошо.

Я трачу много часов, чтобы сделать это самостоятельно, и я также читаю свои посты в Интернете, но не могу найти решение. Пожалуйста, не суди меня. Как я уже сказал, я новичок. Заранее спасибо.

Кстати, я использую json_decode (), когда сначала извлекаю данные, а в конце я использую json_encode (). Но мне не нужно было об этом упоминать.

Этот код будет выдавать желаемый результат (предполагается, что $json содержит JSON из вашего первого фрагмента): 

$arr = json_decode($json);
$buslines = new stdClass();
$routenum = 0;
foreach ($arr->data as $data) {
    foreach ($data->sentenceArray as $route) {
        if (!isset($route->path, $route->path->type, $route->path->nodes)) continue;
        if ($route->path->type != 'bus') continue;
        $buslines->{$routenum} = array();
        foreach ($route->path->nodes as $node) {
            $buslines->{$routenum}[] = $node;
        }
        $routenum++;
    }
}
echo json_encode($buslines);

Выход: 

{
  "0": [
        {"lat":39.952418,"lng":32.85727},
        {"lat":39.952797,"lng":32.856825},
        {"lat":39.953102,"lng":32.856438}
       ],
  "1": [
        {"lat":39.964951,"lng":32.841305},
        {"lat":39.964785,"lng":32.841514}
       ]

Итерация подмассива data, затем итерация sentenceArray, затем, если значение ['path']['type'] равно bus, а подмассив ['path']['nodes'] существует, сохраните этот подмассив как отдельную группу в массиве результатов.

Код: ( Демо ) 

$array = json_decode($json, true);
foreach ($array['data'] as $datas) {
    foreach ($datas['sentenceArray'] as $subitem) {
        if ($subitem['path']['type'] == 'bus' && isset($subitem['path']['nodes'])) {
            $result[] = $subitem['path']['nodes'];
        }
    }
}
echo json_encode($result);

Выход: 

[[{"lat":39.952418,"lng":32.85727},{"lat":39.952797,"lng":32.856825},{"lat":39.953102,"lng":32.856438}],[{"lat":39.964951,"lng":32.841305},{"lat":39.964785,"lng":32.841514}],[{"lat":39.952418,"lng":32.85727},{"lat":39.952797,"lng":32.856825},{"lat":39.953102,"lng":32.856438}],[{"lat":39.964951,"lng":32.841305},{"lat":39.964785,"lng":32.841514}]]

Это также работает с вашей полной входной строкой json, чтобы обеспечить:

Пожалуйста, следуйте ниже код: 

 for($j = 0; $j < $l; $j++) {
    if($sentenceArray[$j]['path']['type'] == "bus") {
        $childArr = array();
        if(isset($sentenceArray[$j]['path']['nodes'])){
            foreach($sentenceArray[$j]['path']['nodes'] as $nodes)
            {
                array_push($childArr, $nodes);
            }
        }
        $arrBus[$j] = $childArr;
    }
}

$arrBus = array_values($arrBus);
$arrBus = json_encode($arrBus);
