It looks like you just need to move your $palindromic_primes array above the lines where you call the function and echo the result.

With how your code is now, you are running the function and trying to echo the sum before your array has been set, so your palindromic_primes aren't being passed into the function.

<?php 
function mimic_array_sum($array){
    $sum=0;
  foreach($array as $element){
         $sum = $sum + $element;                   
     }
    return $sum;
 }
// set the array values
$palindromic_primes = array(11, 757, 16361);

// run the function and pass in the array values set above
$sum = mimic_array_sum($palindromic_primes);

// print the value produced by the function
echo $sum;



?>
