function quiz

Not much detail in the video prior to the quiz, so i am stuck with this. I am missing something?

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

function sum($value){
 array_sum($value)
}

echo $sum($numbers);

Yeah the wording for the challenge is a little confusing. You need to remove/delete the foreach loop. Then set $sum equal to array_sum. Your way would work if you return array_sum from the function and remove the $ from the echo statement, but its kind of a round about way of doing it.
