Php函数使用字符串搜索对象数组

我试图想出一个代码来搜索对象数组中的字符串，如果找到字符串，则获取子菜单对象的值。例如，如果找到字符串“main/dashboard”，则获取子菜单

stdClass Object
(
[type] => single
[slug] => view_admin_dashboard
[menus] => stdClass Object
    (
        [label] => Dashboard
        [icon] => dashboard
        [url] => main/dashboard
    )
[submenus] => Array
    (
        [0] => stdClass Object
            (
                [submenu_slug] => view_all_users
                [label] => View all Users
                [icon] => users
                [url] => main/users/all
            )
        [1] => stdClass Object
            (
                [submenu_slug] => delete_users
                [label] => Delete Users
                [icon] => users
                [url] => main/user/delete
            )
    )
)

我现在有这个，但它在_数组中给我的错误期望参数2是数组

foreach($mainarray as $menus => $menu){
   if(in_array("main/dashboard",$menu)){
      foreach($menu as $submenu){
         echo $submenu->url;
      }
   }
}

也许你想要这样的东西：

foreach($mainarray as $menu){
   if($menu->menus->url == "main/dashboard"){ // if found the url in the object
      foreach($menu->submenus as $submenu)
         echo $submenu->url;
      }
   }
}

什么是

$mainarray

？$main array是使用的整个数组，它不是一个数组，而是一个对象-这就是为什么它在调试输出中显示

stdClass

。如果单词都是大写/小写格式，则解决方案将不起作用。
