PHP中的分页每页仅更新1行

需要帮助修复我的分页。我限制每页显示5行，每次我转到下一页时，它只更新底部的1行，而不是每页显示5个新项目

这是我目前拥有的。抱歉发了这么长的代码。目前，我所做的解决方法是将$listcount设置为1000，以显示所有要同时禁用分页的项

    <?php

            $addtable = ",recommend";

应该是

$curpageoffset = $_REQUEST['offset']*$listcount-1;

当前，如果将起始位置增加到on，则应将其增加页码乘以限制（减1）

currentoffset、listcount、currentpage、totalpages、requestoffset

$currentPage = ceil($requestOffset/$listcount);
if ($currentPage > $totalpages) {$currentpage = 0;}
$currentoffset = $currentPage * $listcount;

然后

这是很多你希望我们阅读的代码我知道@Dagon只是不知道该怎么办如果用户点击2（第2页），页面会更新，并突出显示5（第5页），而不是2。但在URL上显示offset=1这几乎奏效了。谢谢但是，第1页的最后一项显示为第2页的第一项。对不起，我不明白您的意思。你能进一步解释一下吗？谢谢大家!@Xiaosong偏移量应为（当前页码-1）*每页限制$_请求['offset']-1*$listcount；是这样但不起作用吗你是说$_Request['offset']是当前页码吗？如果这样做，sql应该是这样的：limit（$\u REQUEST['offset']-1）*$listcount，$listcount不起作用。一直让我回到第一页
$totalpages = ceil($totalrows/$listcount);
    if ($totalpages > '1') {
        $curpageoffset = 0;
        if (isset($_REQUEST['offset'])) {
            if ($_REQUEST['offset'] >= $totalpages)
                $curpageoffset = $totalpages - 1;
            else if ($_REQUEST['offset']>0)
                $curpageoffset = $_REQUEST['offset'];
        }
        $limitstr = " limit $curpageoffset,$listcount";
    }

$currentPage = ceil($requestOffset/$listcount);
if ($currentPage > $totalpages) {$currentpage = 0;}
$currentoffset = $currentPage * $listcount;

$limitstr = " limit $curpageoffset,$listcount";
