How to get a random single category name in get_posts()?

How can I get a random category name one at a time?? The post may have multiple category instead of a single category. I just want to show a single category name in the post grid loop.

$home_blog_posts = get_posts(array(
    'posts_per_page'    =  3
));

Thanks.

You can use wp_get_post_categories to get the categories from your posts. Then you can use array_rand to get one random category from that array.

Check out these links on how to use wp_get_post_categories and array_rand to suit your needs:
