)The above is an array, which contains the information of the menu. It may have many dimensions. Now there is a question. If the id of a menu is 8, that is, the index is $arr[4]['_child'][5]['_child'][8]. How can I write this menu? Function returns an array that contains all index values. For example, the menu with id 8 returns [4,5,8].

_Child array Just add a parent menu id to each array, and then read it layer by layer through the index, otherwise you have to use a for loop to judge array by array. The effect is too bad
