Can you repost your code with correct formatting using how-to-type-code-in-the-forum and post the question ?

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

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

thanks

Code Wrap your code with 3 backticks (```) on the line before and after. If you specify the language after the first set of backticks, that'll help us with syntax highlighting.

        ```html
        <p>This is code!</p>
        ```

Also, can you repost the actual question you are trying to do ? I cant help if I dont know what is being asked.

The Code should looks like this:

<html>
<body>

```php
<?php

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

?>


<ul>
<?php

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

?>

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

Like in the video before, you have to assign the array_reverse() method into a new variable like $flavors_reversed or something like that.

The second step is to replace the first variable from the foreach loop to a variable with the same identifier defined above.
The variable $list_html over the foreach loop is an empty variable and it's used  for concatenation within the foreach loop.
