what's wrong with my code?

function mimic_array_sum($array) {

    $sum = 0;
    foreach($array as $element) {
    $sum = $sum + 1;
  }
  return $sum;
}

$palindromic_primes = array(11, 757, 16361);
$sum = mimic_array_sum($palindromic_primes);
echo $sum;

?>

This is everything in the code editor when I just passed it again.

Question 2

    <?php 

    function mimic_array_sum($array) {

    $sum = 0;
      foreach($array as $element) {
        $sum = $sum + $element; // Not 1 
    }
      return $sum;
    }



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

    ?>

Question 3

    <?php 

    function mimic_array_sum($array) {

    $sum = 0;
      foreach($array as $element) {
        $sum = $sum + $element; // Not 1 
    }
      return $sum;
    }



    $palindromic_primes = array(11, 757, 16361);
    $sum = mimic_array_sum($palindromic_primes);
    echo $sum;

    ?>

Took me a while but it should be this think you must have had a momentary lapse in concentration 

     function mimic_array_sum($array) {

    $sum = 0;
      foreach($array as $element) {
        $sum = $sum + $element; // Not 1 
    }
      return $sum;
    }

Thank you Adam! Now it worked. I think I was getting ahead of myself, and I was doing question 3 in question 2, and I think that's the reason it wasn't going through.
