How to find the path of a specified key

You want to find a path to a key in a specific array of rules such as the following code to find the Red Fuji key to return an array that includes its parent path array (2, 3, 5, 9)

Master, do me a favor. I've been working on it for a whole day.

$array = Array (1=>array ("name" = "oil"), 2=>array ("name" = "Fruit", "chlids" =>array ("name" = > "Fruit", "chlids" =>array (5=>array ("name" + "Apple", "Childs" =>array (8=>array ("name" = "Green apple",), 9 = >array ("Name" = "Red Fuji",)), 6=>array ("name" = "Orange"), 7=>array ("name" = "Big Pear")), 4=>array ("name" = "Vegetables", "chlids" =>array (3=>array ("name" = "cabbage"), 3=>array ("name" = "celery")));

$r = Find ($array, ' Red Fuji ');p Rint_r ($r); function Find ($ar, $name = ') {  $res = array ();  foreach ($ar as $k + $v) {    if ($v [' name '] = = $name) $res [] = $k;    ElseIf (Isset ($v [' Childs ']) &&! $res) {      $res = find ($v [' Childs '], $name);      if ($res) Array_unshift ($res, $k);    }  }  return $res;}

Array
(
[0] = 2
[1] = 3
[2] = 5
[3] = 9
)

Also please note: Your part of the childs key name is wrong, written in Chlids

Are you still there? My problem is a bit wrong, is to find the Red Fuji key is 9 and then return this result is correct
