我的论坛脚本中出现意外的$end - Unexpected $end in my forum script

所以，我在我的网站上添加了一个论坛部分。到目前为止，每个人的情况都很好。你可以创建一个主题，查看主题列表，但当你去查看一个主题（即view_topic.php?id=#）时，它会不断出现：

Parse error: syntax error, unexpected $end in /home/papervip/public_html/forums/questions/view_topic.php on line 158

因此，以下是view_topic.php的完整脚本（不包括数据库凭据，因此我可以确保我的安全性：D）：

<?php
session_start();
$host="localhost"; // Host name 
$username=""; // Mysql username 
$password=""; // Mysql password 
$db_name=""; // Database name 
$tbl_name="forum_questions"; // Table name 
// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");
// get value of id that sent from address bar 
$id=$_GET['id'];
$sql="SELECT * FROM $tbl_name WHERE id='$id'";
$result=mysql_query($sql);
$rows=mysql_fetch_array($result);

我已经重读了整个文件大约10次了，但它仍然将最后一个结束html标记声明为意外的$end。我是不是忽略了什么？提前谢谢。

我相信这里有一个无与伦比的{：

<body>
<?php if(empty($_SESSION['user'])){
    include("../../header.html");
}else{
    include("../../user/user_header.html");
}  // It looks like this is missing
?>
