functions code challenge

I've got the code to add some of the numbers, but I'm not sure how to go about getting all the numbers to add.

Here is the code:

    <?php

function mimic_array_sum($array) {
    foreach($array as $total) {
        $total = $total + $total;
    }
    return $total;
}
$var = array(1,2,3,4,5);
$total = mimic_array_sum($var);
echo $total;
?>

It's close. But in the foreach loop don't use $total as the temporary variable assigned to the items in the array. Use something like $number because if you use $total as your temporary variable it will reset every time you loop through the array items to the value of the next array item. This will not give you an accurate sum of the items in the array. Also you'll want to initialize the $total variable to 0 just before the foreach loop. This gives ensures that the value of $total starts with 0. Then you can replace one of the $total variables on the right side of your 'sum' equation with the $number variable. Everything else can stay the same.
