我得到它来订购，但现在分页不起作用。现在没有任何内容打印到我的错误日志中。
用户 Red Acid 帮助我解决了缺少的空格并使用字符串变量而不是 PHP_SELF。
一旦我按下下一条记录，我得到:
Not Found
The requested URL /surf/$index.php was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

最佳答案
问题是 ORDER BY 和 DESC 之间没有空格:
$sql="SELECT * FROM $tbl_name ORDER BY ".$_GET["orderby"].$_GET["desc"];
应该是:
$sql="SELECT * FROM $tbl_name ORDER BY ".$_GET["orderby"]." ".$_GET["desc"];
使用字符串变量代替 PHP_SELF:
$scriptname = 'myscript.php'; // OR http://domain.com/myscript.php
echo "<a href=\"$scriptname?page=$last\">Last 10 Records</a>";
