Array_sum is a built in function in php. It's nothing you have to code yourself. And the challenge explicitly states that you need to remove the for loop. The array_sum function does exactly what that for loop is currently doing. What we want to do is to call the fucntion array_sum, pass it in our array, put that value into the $sum variable, and then echo out the result. Take a look at what you need:

<?php

$numbers = array(1,5,8);

$sum = 0;
$sum = array_sum($numbers);

echo $sum;

?>
