那将是一个与数据库相关的问题，通常在 SQL 查询中进行排序。假设您的评论表具有给定的结构，它将是：

SELECT ID, user, author, date, post FROM Comments ORDER BY date DESC LIMIT 0,10

将此附加到您的 sql 语句order by date desc limit 0,20 这应该给您最新的 20 条评论

如果还想显示接下来的20条结果也可以添加OFFSET 20，这样可以帮助你达到加载下一页的效果。

要显示评论，您需要显示它们

<?php
$result=mysql_query("SELECT ID, user, author, date, post TOP number column_name(s) * FROM comments ORDER BY date DESC LIMIT 0,10");
while($row=mysql_fetch_array($result))
 {
   echo $row[4];
 }
 ?>

limit在 mysql 查询或 jquery 中都prepend()可以。
