Your array doesn't have a key associated with it, so the types you are using wont work. Just use regular sort.

sort($flavors);

That should work.

The correct function is array_reverse and requires you to set a new variable for the array. So you'll want to run the function on your flavors array and set it into a new variable, I called mine $flavors_r for "flavors reversed". Then you'll need to adjust the foreach loop to use your new $flavors_r array instead of $flavors.

<?php
$flavors_r = array_reverse($flavors);
    $list_html = "";
    foreach($flavors_r as $flavor) {
        $list_html = $list_html . "<li>";
        $list_html = $list_html . $flavor;
        $list_html = $list_html . "</li>";
    }
    echo $list_html;
?>

In reality, you would not need to set the reversed array into a new variable but for the challenge it is required. You could just overwrite your original array with the reversed order.
