PHP Code Challenge Help

Here is my code:

<code> <?php

function mimic_array_sum($array){

$sum = 17129; foreach($array as $element) { $sum = $sum + $element; } return $element; };

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

?> </code>

I have got to the point in the challenges where it is a guessing game to me. I feel as if PHP is incredibly hard to learn compared to CSS and HTML. ANy help on this would be great. Thanks

I'm not sure exactly what you are trying to accomplish as you seem to be excluding some code. but i can say that you are returning $element which is going to return the last value set during the foreach loop. If you are trying to get the sum of all values in the array passed to the function, return $sum instead. otherwise give a little more detail or code or both. Try to keep all code properly indented and on different lines to prevent mistakes as well.
