<?php

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

$palindromic_primes = array(11, 757, 16361); $sum = mimic_count($palindromic_primes); echo $sum; ?>

FYI, if you're setting a variable to 0, or "", etc, you can just declare the variable without populating it. It can save a couple of bytes ;).

```
<?php
function mimic_array_sum($array) {
$sum; //you can set the array to nothing by just declaring it.
foreach($array as $element) {
$sum = $sum + $element; //the second $sum needs to be $element.
}
return $sum;
}
$palindromic_primes = array(11, 757, 16361);
$sum = mimic_count($palindromic_primes);
echo $sum;
?>
```

21,956 PointsI think you need your first one to be `$sum = $sum + $element`

, so that each time the `foreach`

function is run, it makes the new `$sum`

equal to the previous `$sum`

plus the next `$element`

in the `$array`

.
