# What is the treehouse way of doing this code? It works in my sublime text editor and spits out 17129

I can get the code to work in my sublime text editor but is not excepted in the treehouse check my work. What is the treehouse way of doing this?

palindromic_primes.php
```<?php
function mimic_array_sum(\$array) {
\$total = 0;
foreach(\$array as \$element) {
\$total= \$total + \$element;
}
return \$total;
}
\$sum = "";
\$palindromic_primes = mimic_array_sum(array(11, 757, 16361));
\$sum = \$sum . \$palindromic_primes;
echo \$sum
?>
```

PLUS

Well, you got the function right, but you didn't do what the problem is asking.

use the new mimic_array_sum() function you just wrote. Store the return value in a variable called \$sum

you didn't call the mimic_array_sum function and store its return value to \$sum.

```<?php

function mimic_array_sum(\$array) {
\$total = 0;
foreach(\$array as \$element) {
\$total= \$total + \$element;
}
return \$total;
}

\$palindromic_primes = array(11, 757, 16361);
\$sum = mimic_array_sum(\$palindromic_primes);
echo \$sum;
?>
```
