我有一个递归函数，我从WP得到的响应中排序菜单元素。这是功能：
private function menuBuilder($menuItems, $parentId = 0)
{
$hiddenAttributes = \Config::get('middleton.wp.menuHiddenAttributes');
$res = [];
foreach ($menuItems as &$item) {
$itemParentId = $item->meta->_menu_item_menu_item_parent;
if ($itemParentId == $parentId) {
$children = $this->menuBuilder($menuItems, $item->ID);
if ($children) {
$item['submenu'] = $children;
}
if ($item->post_title == '') {
$item = $this->modifyPostItem($item, $hiddenAttributes);
}
else {
$item->makeHidden($hiddenAttributes)->toArray();
}
$res[$item['ID']] = $item;
unset($item);
}
}
return $res;
}
我从索引函数调用此函数：
public function index()
{
$menus = Menu::all();
$menu = Menu::slug('hovedmeny')->first();
$res = $this->menuBuilder($menu->nav_items);
return $res;
}
如果我做dd($res)，在我返回之前，我会在邮递员中得到这样的结果：

但是，当我从索引函数返回$res时，我得到的实际上是这样的：
{
"2": {
"ID": 2,
"title": "Sample Page",
"slug": "sample-page",
"url": "/page/sample-page",
"status": "publish",
"main_category": "hovedmeny"
},

"ID": 161,
"title": "Hjem",
"slug": "hjem",
"url": "http://ytf.app/?p=161",
"status": "publish",
"main_category": "hovedmeny"
}
}
所以，当我从函数返回它们时，看起来对象的顺序是相反的，为什么是这样，我怎么能用反过来的呢？
