        "rows": [
            {
                "name": "aktiva",
                "digit": "5555.33",
                "rows": [
                    {
                        "name": "balance catalog 1",
                        "digit": "1234.12",
                        "rows": [
                            {
                                "name": "balance subcatalog name 1",
                                "digit": "4321.21",
                                "rows": []
                            },

                        ]
                    },
                    {
                        "name": "balance catalog 2",
                        "digit": "1234.12",
                        "rows": [
                            {
                                "name": "balance subcatalog name 3",
                                "digit": "4321.21",

<?php
function myFunction($value, $key) 
{ 
    // do validation, this will be called for every key, recursively
} 

$arr=array("balance_data"=>array("row"=>"", array("row"=>"2"))); 

array_walk_recursive($arr, "myFunction"); 

?>

This can be achieved using inbuild array_walk_recursive function of php

You would have to write a custom validator for that. Check out this section of the docs here.
