        },

        },
        {
          "card_name": "card 32",
          "id": 10,
          "card_unique_id": "PC10"
        }
      ],
      "BoardId": "PB3"
    },
    {
      "new board": [
        {
          "card_name": "card 40",
          "id": 11,
          "card_unique_id": "PC11"
        }
      ],
      "BoardId": "PB4"
    }
  ]
}

我想在laravel中获取所有卡名.在laravel控制器函数中，我这样编码:它返回一些错误.我不知道如何获取所有这些card_names.

I want to fetch all card name in laravel. In laravel controller function i code like this: It returns some error. I dont know how to fetch all these card_names.

    public function sortupdate(Request $response)
    {
       $get_result_arr = json_decode($response->getContent());

       foreach($get_result_arr as $result){
           $lists = $result->lists;
       }
     }

请任何人帮助. 谢谢进阶.

please anyone help. Thanks Advanced..

推荐答案

将true添加到json_decode()以获得关联数组:

Add true to json_decode() to get an associative array:

$get_result_arr = json_decode($response->getContent(), true);

然后遍历此数组并获取每个card_name:

Then iterate over this array and get each card_name:

foreach ($get_result_arr['lists'] as $list) {
    foreach (array_values($list)[0] as $card) {
        echo $card['card_name'];
    }
}
