is there way can current depth of array? far, had no luck this..

my code:

use app\components\treeview; use app\models\kategorije; $tree = treeview::getmenu();  function recursion($stablo,&$indent) {     $indent++; // try depth of current array     foreach ($stablo $value) {         foreach ($value $key => $value) {             $indent_str = str_repeat("-", $indent);             echo $indent.$value['label'].'<br>';             if (!empty($value['items'])) {                 recursion($value['items'],$indent);             }         };     } } $indent = 0; recursion($tree,$indent);
