Pagination of foreach();

[GrizRule]

I have a blog with the blog entries in a directory (very unsecure, I know) and on my home page I have a foreach(); function that retrieves all of the files (blog entries) from the entries directory. I've posted so many entries, my homepage is taking a very long time to load. Is there any way to paginate this foreach(); function?

 

Here is my code

foreach (glob("entries/*.php") as $filename)
{
    include $filename;
}

$current_page   = isset($_GET['page']) ? intval($_GET['page']) : 1;

$items_per_page = 20;

$offset         = ($current_page - 1) * $items_per_page;

$items          = glob("entries/*.php");

$total_items    = count($items);

$total_pages    = ceil($total_items / $items_per_page);


foreach (array_slice($items, $offset, $items_per_page) as $entry) {

  include $entry;

}
