我有一个维度数组，我想使用array_map添加一个名为“reschedule”的新键
这是我的阵：

$topics = [
  [
     "id" => 1,
     "statusName" => "COMPLETED",
     "lessons" => [
       [
         "id" => 1,
         "statusName" => "COMPLETED"
       ],
       [
         "id" => 1,
         "statusName" => "COMPLETED"
       ],
     ]
  ],
  [
     "id" => 2,
     "statusName" => "SCHEDULED",
     "lessons" => [
       [
         "id" => 1,
         "statusName" => "SCHEDULED"
       ],
       [
         "id" => 1,
         "statusName" => "COMPLETED"
       ],
     ]
  ]
];

我试过的代码：

foreach ($topics as $key => $value) {
    $topics[$key]['lessons'] = array_map(function ($lesson) use ($value) {
        
            $lesson['reschedule'] = true;
            return $lesson;
        
    }, $value['lessons']);
}

我想添加' reschedule '键到每一课，但它不工作，为我的财产。
所需输出：

[
     "id" => 1,
     "statusName" => "COMPLETED",
     "lessons" => [
       [
         "id" => 1,
         "statusName" => "COMPLETED",
         "reschedule" => true 
       ],
       [
         "id" => 1,
         "statusName" => "COMPLETED",
         "reschedule" => true 
       ],
     ]
  ]
