The problem. Due to the recent popularity of “magazine” themes, there’s a high demand from WordPress users who use more than one loop on their blog home page for a solution to avoiding duplicate posts on the second loop.
The solution. Here’s a simple solution to that problem, using the power of PHP arrays.
