我试图将它放到他们点击的哪一行，它将它放在一个名为reply.php的新页面中，但是发生的事情是它只显示最新的内容和主题，而不是来自点击一下。有什么建议？谢谢！

我有一个包含相应数据集的数据库。有任何想法吗？谢谢！

虽然该代码中有很多可以使用的工作，但这主要是你的问题
$query = mysql_query("SELECT * FROM private_messages WHERE to_user='$username'");
while ($row = mysql_fetch_assoc($query)){
$msg_id = $row['id'];
}
看到你在循环的每次传递中覆盖$msg_id，因为除了用户名之外没有其他查询条件，我想你得到id最高的记录，或者你把它放在最新的记录中。

在message.php中，将此行更改为：
$messagesubject = "<div id='center'>
<div id='toggle'><a href='reply.php?id=".$msg_id."'>".$msg_subject."</a></span>
</div>";
