我使用了php分页教程：http://www.phpeasystep.com/phptu/29.html。而且它说很容易我没想到会有任何问题。但是，我遇到过一个。现在我知道最好的结果你应该看到我的源代码，所以我将提供它。问题是它查询正常并且只在页面上显示某些数据，如果成员是正确的并且每页只限制几个...但是当我尝试更改以查看下一个更多注释时它不会更改值页。

我怀疑问题可能是我的$ targetpage，它会打开配置文件的不同数据，具体取决于每个不同用户的ID。但是我不知道如何纠正这个问题，或者这是否是问题......任何人都可以看到错误吗？ （FIXED）

是的，$targetpage不正确：
$targetpage = "profile.php?id=$id";
会产生类似profile.php?id=42的内容。然后，在您的网址中使用该字符串：
<a href=\"$targetpage?page=$counter etc..." />
为您提供实际生成的HTML：
<a href="profile.php?id=42?page=XXX" />
这是不正确的。查询字符串应该只有一个?。您需要将&用于后续参数，例如：
<a href=\"$targetpage&page=$counter etc..." />
^--- &, not ?

您的SQL查询应包含TOP和LIMIT值，因此您可以选择所需的范围（页面）。类似的东西：
$items_per_page = 10;
$query = "SELECT TOP $items_per_page * FROM table LIMIT ". $items_per_page * $REQUEST['page'];
