How can categories be displayed instead of forums in the category bars on a PHP forum homepage?

To display categories instead of forums in the category bars on a PHP forum homepage, you can modify the code that generates the category bars to only display categories. This can be achieved by querying the database for categories only and then looping through the results to display them in the category bars. 

// Query the database for categories
$categories = mysqli_query($conn, "SELECT * FROM categories");

// Loop through the categories and display them in the category bars
while ($category = mysqli_fetch_assoc($categories)) {
    echo '<div class="category-bar">' . $category['category_name'] . '</div>';
}
