Hello
I need to get the ID of the forum last active author, how can I do it?

[Robin W]

$author = bbp_get_author_link( array( 'post_id' => bbp_get_forum_last_active_id($forum_id)) ;

Thanks for answer. Unfortunately I want to get only user ID number. I want use this to do something like this:

$last_author = id_of_the_forum_topic_last_active_user
$user = get_user_by('login',$last_author);
if (is_user_online($user->ID)) {
} else {
}

What do I need to put in place of the id_of_the_forum_topic_last_active_user?

$post_id = bbp_get_forum_last_active_id($forum_id)) ;
$last_author  = get_post_field ('post_author', $post_id);
