มีปัญหาเกี่ยวกับการ paging ค่ะ คือจำนวนข้อมูลเยอะทำให้ไม่สวยงาม

<?php
require_once 'class.pagination.php'; // include class

$pageNum = 1 //หน้าปัจจุบัน อาจจะรับค่าจาก $_GET['page']
$perPage = 10//จำนวนข้อมูลต่อหน้า
$row['numrows'] = 100 //จำนวนข้อมูลทั้งหมด

$page = new pagination($pageNum, $perPage, $row['numrows'],$_SERVER['PHP_SELF']);
echo $page->getPagination();
?>
