将数组数据传递给batchWriteItem

Question

我有这个并且它工作正常：

$response = $dynamodb->batchWriteItem([
      'RequestItems' => [
         'my_table' => [
            [
                'PutRequest' => [
                  'Item' => ['ID' => ['N' => '120']]
                ],
                'PutRequest' => [  ///Entire PutRequest array need to be repeated not just item array///
                  'Item' => ['ID' => ['N' => '125']]
                ]
            ]
        ],
    ]
]);

如何将数组传递给my_table？
