Refactoring the Codebase

Q: 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.

A: ''' <html> <body> <?php

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

I am not sure what exactly I am doing wrong :/

You need to set the reverse array like you have done and then use this in the foreach loop to echo out the flavors in reverse order

<html>
<body>
<?php

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

?>
<ul>
<?php

        $reverse = array_reverse($flavors);

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

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