如何在多维数组中使用array_walk_recursive更改键名

Question

我可以使用array_walk_recursive函数来修改某些特定的值，比如这个

array_walk_recursive($arr, function (& $item, $key) {
    if($key === 'name') {
        $item = 'some value';
    }
});

但是我如何修改密钥名称本身，它不能与$ key的引用一起工作。请帮帮我。

$ arr here

$arr = [
  0 =>  [
    "id" => 1,
    "name" => "departmentName",
    "code" => "1",
    "orderNumber" => 1,
    "enabled" => true,
    "createSpace" => false,
    "description" => "balabala",
    "lft" => 1,
    "lvl" => 0,
    "rgt" => 4,
    "children" => [
      0 => [
        "id" => 7,
        "name" => "departmentName_ProblemHere",
        "code" => "7",
        "orderNumber" => 7,
        "enabled" => true,
        "createSpace" => false,
        "description" => null,
        "lft" => 2,
        "lvl" => 1,
        "rgt" => 3,
        "children" => []
      ]
    ]
  ],
  1 => [
    "id" => 2,
    "name" => "departmentName",
    "code" => "1",
    "orderNumber" => 2,
    "enabled" => true,
    "createSpace" => false,
    "description" => null,
    "lft" => 1,
    "lvl" => 0,
    "rgt" => 2,
    "children" => []
  ],
  2 => [
    "id" => 3,
    "name" => "departmentName",
    "code" => "1",
    "orderNumber" => 3,
    "enabled" => true,
    "createSpace" => false,
    "description" => null,
    "lft" => 1,
    "lvl" => 0,
    "rgt" => 2,
    "children" => []
  ],
  3 => [
    "id" => 4,
    "name" => "departmentName",
    "code" => "4",
    "orderNumber" => 4,
    "enabled" => true,
    "createSpace" => false,
    "description" => null,
    "lft" => 1,
    "lvl" => 0,
    "rgt" => 2,
    "children" => []
  ],
  4 => [
    "id" => 5,
    "name" => "departmentName",
    "code" => "5",
    "orderNumber" => 1,
    "enabled" => true,
    "createSpace" => false,
    "description" => null,
    "lft" => 1,
    "lvl" => 0,
    "rgt" => 2,
    "children" => []
  ],
  5 => [
    "id" => 6,
    "name" => "departmentName",
    "code" => "6",
    "orderNumber" => 6,
    "enabled" => true,
    "createSpace" => false,
    "description" => null,
    "lft" => 1,
    "lvl" => 0,
    "rgt" => 2,
    "children" => []
  ]
];

甚至可能更深，它是一个动态的树。

如下所示的预期结果，只需更改所有＆＃34; name＆＃34; ＆＃34; text＆＃34;的关键。

$arr = [
  0 =>  [
    "id" => 1,
    "text" => "departmentName",
    "code" => "1",
    "orderNumber" => 1,
    "enabled" => true,
    "createSpace" => false,
    "description" => "balabala",
    "lft" => 1,
    "lvl" => 0,
    "rgt" => 4,
    "children" => [
      0 => [
        "id" => 7,
        "text" => "departmentName_ProblemHere",
        "code" => "7",
        "orderNumber" => 7,
        "enabled" => true,
        "createSpace" => false,
        "description" => null,
        "lft" => 2,
        "lvl" => 1,
        "rgt" => 3,
        "children" => []
      ]
    ]
  ],
  1 => [
    "id" => 2,
    "text" => "departmentName",
    "code" => "1",
    "orderNumber" => 2,
    "enabled" => true,
    "createSpace" => false,
    "description" => null,
    "lft" => 1,
    "lvl" => 0,
    "rgt" => 2,
    "children" => []
  ],
  2 => [
    "id" => 3,
    "text" => "departmentName",
    "code" => "1",
    "orderNumber" => 3,
    "enabled" => true,
    "createSpace" => false,
    "description" => null,
    "lft" => 1,
    "lvl" => 0,
    "rgt" => 2,
    "children" => []
  ],
  3 => [
    "id" => 4,
    "text" => "departmentName",
    "code" => "4",
    "orderNumber" => 4,
    "enabled" => true,
    "createSpace" => false,
    "description" => null,
    "lft" => 1,
    "lvl" => 0,
    "rgt" => 2,
    "children" => []
  ],
  4 => [
    "id" => 5,
    "text" => "departmentName",
    "code" => "5",
    "orderNumber" => 1,
    "enabled" => true,
    "createSpace" => false,
    "description" => null,
    "lft" => 1,
    "lvl" => 0,
    "rgt" => 2,
    "children" => []
  ],
  5 => [
    "id" => 6,
    "text" => "departmentName",
    "code" => "6",
    "orderNumber" => 6,
    "enabled" => true,
    "createSpace" => false,
