php calculate sum of all values ​​in multidimensional array

php built-in function array_sum() function returns the sum of all values ​​in the array, and can only return the sum of one-dimensional arrays;

To calculate the sum of all values ​​in a multi-dimensional array, a custom function is required;

1function get_sum($array) {
2$num = 0;
3foreach($arrayas$k => $v) {
4if(is_array($v)) {
5$num += get_sum($v);
6        }
7    }
8return$num + array_sum($array);
9 }
10 get_sum($array);

The above introduces PHP to calculate the sum of all values ​​in a multi-dimensional array, including aspects of the content. I hope it will be helpful to friends who are interested in PHP tutorials.
