just get all the categories on mysql with a query like:

"SELECT name from category"

don't know if you are using PDO or any other any driver like mysqli, I assume the table's name is called category. set the content to a variable and loop through it.

<ul>
    <?php  foreach ($categories as $category): ?>
        <li><?=$category ?></li>
    <?php endforeach; ?>;
</ul>
