我有這樣的數據集：$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 ( ) ))我只需要獲取事件并刪除空事件。然而，首先我嘗試獲取像這樣的事件，但它給出了一個錯誤。 $new = []; for($i=0 ; $i < count($data)-1 ; $i++) { if(count($data[$i]['events']) > 0) { $new[] = $data[$i]['events']; } } print_r ($new);但它給了我一個錯誤： Cannot use object of type Illuminate\Http\JsonResponse as array誰能幫我解決這個問題嗎？

你需要解碼$data[0]而不是$data因為你正在做
$data[] =
同樣的 for 循環，你應該這樣做
if(count($data[0][$i]['events']) > 0)
回首憶惘然

您可以像這樣使用 Laravelcollect() 方法：
collect($your_array)->toJson();
