Hi, chaps...
Don't know whats wrong with my code in this challenge...
here's what I have:
<?php
function mimic_array_sum($array){
$sum = 0;
foreach($array as $element){
$sum = $sum + $element;
}
echo = $sum;
};
$palindromic_primes = array(11, 757, 16361);
?>
any idea?
Thanks

- A link to the code challenge you are having issues with
- A "working" example using a PHP sandbox

What I do see is it looks like $array is not defined anywhere. Is $palindromic_primes supposed to be $array?
Randy Hoyt
Treehouse Guest TeacherHey Alejandro,
The instructions say to have the mimic_array_sum function() return the sum. Right now, your function is echo'ing it instead.
Does that help?

Perhaps each challenge should have a link to it's own forum/help topic. This would reduce redundant posts. Hey, that is kinda like PHP. I'm learning!

Treehouse Guest TeacherHa Matthew! Exactly. :~) I like this idea about linking to the forums: I'll pass that idea along.
