Sum of a row of an associative array using PHP?

Question

Is there a php function that returns the sum of a row of an associative array?

If not should I just use a counter and a foreach loop?

Appreciate it!

Answer 1

To get the sum based on a certain column key, use this:

array_sum(array_column($assoc_array, 'key_name'));

Answer 2

array_sum will work for you.

$arr = array(
     'key1' => 54.3,
     65 => 10
);
$sum = array_sum($arr);
