只有下一个和上一个按钮的简单分页

Question

只是有一个简单的问题.这是在我的某个网站中使用的分页代码.我只是想让这更简单.删除所有页码,只需保留"下一步"和"上一页"链接.

任何人都可以指出我需要删除脚本的哪一部分来摆脱页码.非常感谢您的帮助.

看看下面的代码,最短的php分页脚本

<?php
$totalpage      = 10;
$currentpage    = (isset($_GET['page']) ? $_GET['page'] : 1);
$firstpage      = 1;
$lastpage       = $totalpage;
$loopcounter = ( ( ( $currentpage + 2 ) <= $lastpage ) ? ( $currentpage + 2 ) : $lastpage );
$startCounter =  ( ( ( $currentpage - 2 ) >= 3 ) ? ( $currentpage - 2 ) : 1 );

if($totalpage > 1)
                {
                    $pagination .= '<ul class="paginate" id="paginate">';
                    $pagination .= '<li><a  href="http://magento13.localhost.com/pagination.php?page=1" class="paginate_click" id="1-page">First</a></li>';
                    for($i = $startCounter; $i <= $loopcounter; $i++)
                    {

                        $pagination .= '<li><a  href="http://magento13.localhost.com/pagination.php?page='.$i.'">'.$i.'</a></li>';
                    }
                    $pagination .= '<li><a href="http://magento13.localhost.com/pagination.php?page='.$totalpage.'" class="paginate_click" id="'.$totalpage.'-page">Last</a></li>';
                    $pagination .= '</ul>';
                }
echo $pagination;

?>
