 * Hi
 * Have a bit of a brainteaser, wonder if anyone smart enough can help me out; I’ve
   got a single post page that displays a singe post 🙂
 * But underneath I wish to display posts in the same category, I have the code 
   below, which works, HOWEVER 🙂 I want it to exclude the current post AND exclude
   duplicates of posts, as for example I want to be able to tag a post in multiple
   categories but other posts might be in multiple categories also, so it might 
   bring in multiple copies of the same post;
 * Does that make sense? Hopefully it does
 * Thanks for any help
 *     ```
       <?php
       	global $post;
       	$categories = get_the_category();
       	foreach ($categories as $category) :?>
       		<?php
       			$posts = get_posts('numberposts=3&category='. $category->term_id);
       			foreach($posts as $post) : ?>
   
       			<li>
       				<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
       			</li>
   
       		<?php endforeach; ?>
       <?php endforeach; ?>
       ```

 * You need to progressively build an array of post IDs that is passed as the ‘post__not_in’
   argument for each iteration of `get_posts()`. The first time through, the array
   only contains the current post ID. As each link is output, add the corresponding
   ID to the array. Thus the next category query will not have any duplicates from
   the first category. Rinse and repeat 😉
 * You will need to convert your `get_posts()` arguments to the array format, you
   cannot mix string and array formats. I always recommend everyone abandon the 
   string in favor of array for all cases. It’s less error prone, easier to read
   and maintain, and certain query arguments will only work with the array format.
