分析错误:语法错误，意外$end-不知道我的代码哪里错了

Question

这是我的代码，它给了我一个意外的$end错误，我似乎不知道为什么。

我以为这可能是因为包含的文件，但我在运行代码时遇到了同样的错误，并对所需的文件行进行了注释。上面说错误在最后一行。

<?php
//mysql and functions

require ("dbconnect.php");
require ("functions.php");
//start session
session_start();
//authenticate session - PART I
if (!isset($_SESSION['email']))
{
    echo "Please login.. Redirecting";
    header("refresh:2;url=login.php");
    die();
}
else
{
    //session data
    $email = $_SESSION['email'];
    $firstname = $_SESSION['firstname'];
    $lastname = $_SESSION['lastname'];
    //check session data in database for second authentication
    $check = mysql_query("SELECT * FROM users WHERE email='$email' AND 
        firstname='$firstname' AND lastname='$lastname'") or die(mysql_error());
    if(is_resource($check) and mysql_num_rows($check)>0)
    {
        //success
    }
    else
    {
        echo "Session Expired. Login Again.";
        header("refresh:2;url=login.php");
        die();
    }
    echo "Hi, This is protected content that is only for logged in members.";
?>

如果在我之前的重新缩进中看不到它，那么在末尾会缺少一个}，从而结束else。
