如何用PHP根据二维数组键值下标生成新的数组？

[
  1 => [
    0 => '测试-2票',
    1 => '小白-2票',
    2 => '张张-2票'
  ],
  2 => [
    0 => '颜夕-2票',
    1 => '小黑-2票',
    2 => '小黄-2票'
  ],
  3 => [
    0 => '小绿-2票'
  ]
]

[
  [ '测试-2票', '颜夕-2票' ],
  [ '小白-2票', '小黑-2票' ],
  [ '张张-2票', '小黄-2票', '小绿-2票' ]
]

$arr = [
  1 => [
    0 => '测试-2票',
    1 => '小白-2票',
    2 => '张张-2票'
  ],
  2 => [
    0 => '颜夕-2票',
    1 => '小黑-2票',
    2 => '小黄-2票'
  ],
  3 => [
    0 => '小绿-2票'
  ]
];

$result = array_map(function (...$list) {
  return $list;
}, ...$arr);

var_dump($result);

array(3) {
  [0] => array(2) {
    [0] => string(18) "测试-2票"
    [1] => string(18) "颜夕-2票"
  }
  [1] => array(2) {
    [0] => string(18) "小白-2票"
    [1] => string(18) "小黑-2票"
  }
  [2] => array(3) {
    [0] => string(18) "张张-2票"
    [1] => string(18) "小黄-2票"
    [2] => string(18) "小绿-2票"
  }
}

$result = array_map(fn(...$i) => $i, ...$arr);
var_dump($result);
