无法在 Laravel 中使用 Illuminate\\Http\\JsonResponse
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。然而，首先我尝试获取像这样的事件，但它给出了一个错误。
$new = [];
for($i=0 ; $i < count($data)-1 ; $i++)
{
if(count($data[$i]['events']) > 0)
{
$new[] = $data[$i]['events'];
}
}
print_r ($new);
但它给了我一个错误： Cannot use object of type Illuminate\Http\JsonResponse as array
谁能帮我解决这个问题吗？

你需要解码$data[0]而不是$data因为你正在做$data[] =同样的 for 循环，你应该这样做if(count($data[0][$i]['events']) > 0) -

您可以像这样使用 Laravelcollect() 方法：collect($your_array)->toJson();https://laravel.com/docs/7.x/collections
