Sum of associative array string using PHP?

Question

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

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

Appreciate it!

Answer 1

array_sum will work for you.

$arr = array(
     'key1' => 54.3,
     65 => 10

$sum = array_sum($arr);
