PHP Enhancing a Simple PHP Application Refactoring the Codebase Manipulating an Array

my array_reverse doesn't work

This block of code creates an array of ice cream flavors and displays them in ascending order. The owner of the ice cream shop would like this order changed so that the flavors are displayed in descending order instead, starting with Cookie Dough first and Jalapeno So Spicy last. Leave the $flavors array itself in the same order, but modify something else in this code block to achieve that.

i just add the var with array_reverse and changed $flavors in the foreach with my var but doesn't work

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

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

<ul>
<?php

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

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

What you do is a way to achieve the result, but they don't expect you to do that this way. You have to yo use the array_reverse function directly inside the foreach.

If you read carefully the instructions It says:

Leave the $flavors array itself in the same order, but modify something else in this code block to achieve that.

What you need to modify is this snippet of code:

<?php

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

?>
