Code challenge - reversing the order of an array.

I thought that the array function, array_reverse was the key to this challenge

index.php 
<html>
<body>
<?php

$flavors = array(
        "Jalapeno So Spicy",
        "Avocado Chocolate",
        "Peppermint",
        "Vanilla",
        "Cake Batter",
        "Cookie Dough"
    );
array_reverse($flavors);
?>
<ul>
<?php

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

?>
</ul>
</body>
</html>

It is, but it returns a new array with the items reversed. The original array stays in the same order. Try:

$flavors_reversed = array_reverse($flavors);

Thank you. Your advice was very helpful. It took me a few minutes, but I finally figured out that in addition to setting up the reversed array in a new variable, $flavors_reversed, I also had to sub it for $flavors to display the reversed array results.
