What is wrong with my code?

Where is my mistake? Why can't I pass?


$sum = 0;
function mimic_array_sum($array) {
  foreach($array as $element) {
    $sum = $sum + $element;
    return $sum


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

You are returning the $sum variable inside of the foreach loop. Move the return statement outside of the loop, but keep it inside of the function. I would also move the $sum = 0 inside of the function, before the foreach loop because in the next step of the challenge you will have to create a variable called $sum outside of the of the function.
