多维数组中的求和值?

I just have no idea how to sum and echo values in multidimensional array. This is my array with info about order.

I need to sum RESULT_VALUE and echo one united DESCR list. I have tried lots of things but nothing, never worked with that kind of arrays levels. This is an array with two different products with applied discounts.

Array
(
    [0] => Array
        (
            [ORDER_ID] => 35
            [DISCOUNT_ID] => 18
            [ORDER_COUPON_ID] => 0
            [COUPON_ID] => 
            [RESULT] => Array
                (
                    [BASKET] => Array
                        (
                            [617] => Array
                                (
                                    [RULE_ID] => 248
                                    [APPLY] => Y
                                    [RULE_DESCR_ID] => 248

    You can use array_walk_recursive to get result. Code below sum all values of key $key wherever they are in the array

    $key = 'RESULT_VALUE';
    $sum = 0;
    array_walk_recursive ($array, 
             function($v, $k, $key) use (&$sum) { 
                 if($k === $key) { $sum += $v;}}, 
             $key);
    
    echo $sum;

    You can use array_sum and array_column.

    Array_column grabs all values from one column in the array, and array_sum... Sums it...

    echo array_sum(array_column($arr, "RESULT_VALUE"));
