Getting the post category in functions.php?

  • I have a custom function to make an excerpt for our posts, and in that function I can get the post title like this:

    $post_title = get_the_title();

    And the text of the post with this:

    $text = get_the_content(”);

    But for various reasons I need to get the category of the post, and I don’t see how to do that.

    Any advice for that?
