PHP Functions 2/3 Sum of all numbers in an array using foreach

The task wants me to return the sum of all the numbers in the array below.

I think I'm having some issues with the foreach loop and the $element variable.

Here is my code

<?php

function mimic_array_sum($array){ foreach($array as $element){ $total = $array as $element; } return $total;

}

$palindromic_primes = array(11, 757, 16361);

echo mimic_array_sum($palindromic_primes);

?>

I think the issue is with the line here

$total = $array as element;

This would probably give an error. I think this might be what you're looking for:

$total = $total + $element;

or

$total += $element;
