有人可以建议如何解决这个问题吗？

我想从我的 SHOUTBOX 表中按 id 调用前 50 行，但按升序将它们显示在 div 中（最近的行（最新的）在底部）

例如;

最近的行是 id 200，我想调用第 150 - 200 行，将它们显示在 div 中；

150, 151, 152, . . 。ETC 。. 200 <<< DIV 中的最后一行

我的 PHP 代码目前看起来像这样；

$recall=mysql_query("SELECT *, DATE_FORMAT(timepost,'%H:%i:%s') as timepost FROM shoutbox ORDER BY id DESC LIMIT 50");

    while($comm=mysql_fetch_object($recall)){
      if ($comm->poster == "System"){
      print"<font color=#3399FF>$comm->timepost-<strong><a href='profile.php?viewuser=$comm->poster' target='iframecontent'><font color=#3399FF>$comm->poster</font></a></strong>: </font>";
    echo replace($comm->post);
    echo"<br>";
      }

但它会在 div 中返回我的数据，例如；

200、199、198、. . 。ETC 。. 150 <<< DIV 中的最后一行

请问有人可以帮忙吗？

注意：我目前正在浏览我的所有页面并将所有 mySQL 查询转换为 PDO

替换ORDER BY id DESC为ORDER BY id

For future reference, if you're converting to PDO there is the exact answer for reading backwards on this page without changing your query. http://www.php.net/manual/en/pdostatement.fetch.php.

For now this will work:

SELECT *, DATE_FORMAT(timepost,'%H:%i:%s') AS timepost FROM (SELECT * FROM shoutbox ORDER BY id DESC LIMIT 50) AS foo ORDER BY id ASC

Ok, try this:

$recall=mysql_query("SELECT *, DATE_FORMAT(timepost,'%H:%i:%s') as timepost FROM (SELECT * FROM shoutbox ORDER BY id DESC LIMIT 50) ORDER BY id ASC");

You have wrong the order command, you have to put ASC instead of DESC Here is your correct query:

$recall=mysql_query("SELECT *, DATE_FORMAT(timepost,'%H:%i:%s') as timepost FROM shoutbox ORDER BY id ASC LIMIT 50");

    while($comm=mysql_fetch_object($recall)){
      if ($comm->poster == "System"){
      print"<font color=#3399FF>$comm->timepost-<strong><a href='profile.php?viewuser=$comm->poster' target='iframecontent'><font color=#3399FF>$comm->poster</font></a></strong>: </font>";
    echo replace($comm->post);
    echo"<br>";
      }

Change your query to:

$recall = mysql_query("SELECT *, DATE_FORMAT(timepost,'%H:%i:%s') as timepost 
   FROM shoutbox ORDER BY id ASC LIMIT 50");
