php - 无法将类型Illuminate\\Http\\JsonResponse的对象用作Laravel中的数组

Question

我有这样的数据集:

$data[] =
Array
(
    [u_d] => ABCDEF
    [0] => Array
        (
        [one] => oned
        [two] => 222
        [three] => three
        [four] => 444
        [five] => 555
        [events] => Array
            (
                [0] => Array
                    (
                        [feed] => Array
                            (
                                [0] => Array
                                    (
                                        [date-time] => 191018080000
                                        [sub-type] => abc
                                        [comments] => test comments
                                        [parameter-list] => para1, para2
                                        [state] => bad
                                        [value] => 1000
                                    )

                            )

                    )

            )
        )


    [1] => Array
        (
            [one] => two
            [two] => 224562
            [three] => thyyree
            [four] => 445344
            [five] => 5345355
            [events] => Array
                (
                )

        )
)

我只需要获取事件并删除空事件。但是，首先我试图获取喜欢的事件，但是却给出了错误。

                               $new = [];
                                 for($i=0 ; $i < count($data)-1 ; $i++)
                                {
                                  if(count($data[$i]['events']) > 0)
                                  {
                                    
                                    $new[] = $data[$i]['events'];
                                   
                                  }
                                  
                                }
                                print_r ($new);

但这给了我一个错误:不能使用Illuminate \ Http \ JsonResponse类型的对象作为数组
谁能帮我解决这个问题？
谢谢

您需要解码 $ data [0] 而不是 $ data ，因为您要这样做

$data[] =

同样的循环，你应该做

if(count($data[0][$i]['events']) > 0)
