function lost($mimic_array_sum)

I keep getting step 2 of the code challenge wrong. Usually, I can get close enough that I'm given a hint. I'm so far off that all I get is "Bummer! Try again!" ("Bummer" is not very helpful). If I had to guess, I think I'm misunderstanding the difference between my function variables, my working variables, my argument, and my variables outside the function.

 <?php 

function mimic_array_sum($array) {

    $sum = 0;
    foreach($array as $element) {
    $sum = $sum + $array; 
    }
    return $sum;  
}
$palindromic_primes = array(11, 757, 16361);
$sum = mimic_array_sum($palindromic_primes);
echo $sum;
?>

OK Chris,

You are soooo close. You have a working variable ($element) you are not using. In the statement inside the foreach loop replace $array with $element.
