how to calculate data in multidimensional array php

guys is that possible to calculate between (+,-,*,/) in multidimensional array?

example i have a multidimensional array in $menu_info with this following code : 

array(3) {
  [0]=>
  array(5) {
    ["menu_order_id"]=>
    string(3) "190"
    ["menu_name"]=>
    string(13) "Golden Salmon"
    ["menu_variant"]=>
    string(0) ""
    ["qty"]=>
    string(1) "1"
    ["price"]=>
    string(4) "15.4"
  }
  [1]=>
  array(5) {
    ["menu_order_id"]=>
    string(3) "191"
    ["menu_name"]=>
    string(13) "Golden Salmon"
    ["menu_variant"]=>
    string(0) ""
    ["qty"]=>
    string(1) "1"
    ["price"]=>
    string(4) "15.4"
  }
  [2]=>
  array(5) {
    ["menu_order_id"]=>
    string(3) "192"
    ["menu_name"]=>
    string(13) "Golden Salmon"
    ["menu_variant"]=>
    string(0) ""
    ["qty"]=>
    string(1) "1"
    ["price"]=>
    string(4) "15.4"
  }
}

You can try this:

$sum = array_sum(array_map(function($item) {
    return $item['price']*$item['qty'];
}, $menu_info));

With some more explanation on your specific issue, I may be able to assist you in better alternatives.
