Sum of Specific Values in Multi-Dimensional Array

[Phil-man]

Hi. I have an array that consists mostly of other arrays (so I guess it's a multidimensional array). In fact, only the first element in the main array is NOT an array; the rest of the elements are, and they all contain the same type of data. I need to get the sum of, for example, the 2nd value of all of the arrays. How would I do that? Is there some variation of array_sum that lets you get a sum of values across multiple arrays as opposed to getting a sum of the values in a single array? Thanks for any help!

seems there is no such function you expected.
but this code may help you
suppose the multidimensional array like this

$data = array(
    1,
    array(2, 3, 4),
    array(5, 6),
    array(7, 8, 9, 10)
); 

then

function get_second_element(&$data) {
       if (is_array($data) && sizeof($data) >= 2) {
           return $data[1];
       }
}
echo $sum = array_sum(array_map('get_second_element', $data)); 

output 17

Perfect. Thanks!!
