Write the code inside this mimic_array_sum() function. That code should add up all individual numbers in the array and r

I wonder why the code is not working? I think it is correct:

<?php function mimic_array_sum(){ $sum = 0; foreach($array as $number) { $sum = $sum + $number; } return $sum; }

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

?>

You are close, but you didn't declare the function perimeter.

    function mimic_array_sum($array){ // Don't forget the perimeter.
        $sum = 0;
        foreach($array as $number) {
            $sum = $sum + $number;
        }

        return $sum;
    }

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