The following code is resulting in an error message that no value is returned. Since there is a return command at the end of the function, it should return $total. I am stumped on this.
<?php function mimic_array_sum ($array) { $total = 0; foreach ($array as $element) { $total = $total + $array[$element]; } return $total; } $palindromic_primes = array(11, 757, 16361); ?>

I'm thinking that your function is returning an undefined value.
You have $total = $total + $array[$element];
Your working variable $element already contains a number from the array. You're then trying to use that as an index into the array and add that result to $total.
It should be $total = $total + $element;
