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)
回首忆惘然

您可以像这样使用 Laravelcollect() 方法:
collect($your_array)->toJson();
