How is this generating 6?

```    <?php

\$numbers = array(1,2,3,4);

\$total = count(\$numbers);

\$sum = 0;

\$output = "";

\$i = 0;

foreach(\$numbers as \$number) {

\$i = \$i + 1;

if (\$i < \$total) {

\$sum = \$sum + \$number;

}

}

echo \$sum;

?>
``` PLUS

Hey Paul,

You're getting a sum of 6 because your \$total variable is equal to 4, as there are 4 values in your \$numbers array. In your if statement, when \$i = 3, 3 is less than 4, so the first 3 values of \$numbers gets added together, 1 + 2 + 3 = 6. If you want the last value accounted for, you can use

```if(\$i <= \$total) { \$sum = \$sum + \$number; }
```

Hope that helps! I see. Each of the \$numbers array gets put into the working variable \$numbers. On the first iteration, \$number + \$sum = 1. On the second iteration, \$sum = 3, and the final iteration is 6 (while 3 < 4).
