How can PHP be used to determine the number of entries that exist only on the last page of a display?

To determine the number of entries that exist only on the last page of a display, you can calculate the total number of entries and the number of entries per page. Then, find the remainder of the total number of entries divided by the number of entries per page to determine how many entries are on the last page.

$total_entries = 100; // total number of entries
$entries_per_page = 10; // number of entries per page

$last_page_entries = $total_entries % $entries_per_page;
echo "Number of entries on the last page: " . $last_page_entries;
