Php 分页错误

显示ASC到DESC的分页为：

if($page == 1) { $pstart = 0; } else { $pstart = $page * $totalrows; }
$pend = $pstart + $totalrows; 

HTML代码是从ASC到DESC的

<form action="<?=$_SERVER["SCRIPT_NAME"];?>" method="get">
    <div>

    <a class="page-numbers" href="<?=$_SERVER["SCRIPT_NAME"];?>?p=<?=$page + 1;?>">Next</a>
     <input class="page-numbers" name="p" type="text" value="<?=$page + 1;?>" /> <input class="page-numbers" type="submit" value="Jump" />
     </div>

     </form>

我应该更改哪些php代码，因为要显示ASC POST的DESC和显示接下来10篇POST的分页，请更改限制部分（语法为限制偏移，行计数）

您可以使用sqllimit命令将自己限制为10个结果并传递一个偏移量。 另外，您的代码

if（$page==1）{$pstart=0；}否则{$pstart=$page*$totalrows；}
$pend=$pstart+$totalrows

不正确-对于第1页，$pstart将为0，但是对于第2页，$sptart将为20，使您跳过记录10-19

$sql = "SELECT posts.Tags as tags, posts.OwnerUserId as postsid, posts.Id as postid, posts.Body as body, posts.Title as title, users.Id as userid, users.DisplayName as usersname FROM posts JOIN users ON posts.OwnerUserId = users.Id WHERE posts.Id >= " . $pstart . " AND posts.Title != '' ORDER by posts.Id DESC LIMIT " . $totalrows;

$sql = "SELECT posts.Tags as tags, posts.OwnerUserId as postsid, posts.Id as postid, posts.Body as body, posts.Title as title, users.Id as userid, users.DisplayName as usersname FROM posts JOIN users ON posts.OwnerUserId = users.Id WHERE posts.Id >= " . $pstart . " AND posts.Title != '' ORDER by posts.Id DESC LIMIT " . (($page-1) * $totalrows) .",". $totalrows;
