 * Hi
    I need an array of all author ids of the found posts. With get_posts() i 
   get everything but i need only the author ids and only each one time and the 
   full list, not only 5 or anything. Whats the code for that?

 * try:
 *     ```
       $all = get_posts('posts_per_page=-1');
       $author_ids = array_unique( wp_list_pluck( $all, 'post_author' ) );
       var_dump( $author_ids );
       ```
