ARGHHHHH pagination, again? I know!
OK here is a code that I worked on to get a grocery store items list displayed in a table in a paginated design. Everything is working fine except I don't know how to dynamically display auto incremented indexID range on that particular page, like 1-10 11-20 21-30 31-40 and so on (something like amazon items in cart) instead of page numbers << < 1 2 3 4 > >> as pagination hyperlink to move between different pages. Any help will be greatly appreciated.

$sql = "SELECT COUNT(*) FROM store";
$result = mysql_query($sql, $conn) or trigger_error("SQL", E_USER_ERROR);

$numrows = $r[0];
// number of rows to show per page
$rowsperpage = 10;
// find out total pages
$totalpages = ceil($numrows / $rowsperpage);
