谁能告诉我为什么 PHP 给我这个错误？：

Parse error: syntax error, unexpected 'else' (T_ELSE) in C:\xampp\htdocs\Task2PHP\final\registration.php on line 139

（错误是*中的错误，因为我没有输出所有代码）

我似乎找不到问题

代码：

<?php

if ($isLoggedin === false) {

                                include("form.php");


                                    if (isset($_POST['Name'])) {

                                        // DECLARE VARIABLES TO NULL
                                        $Name = null; $Surname = null; $Username = null; $Email = null; $C_Email = null; $Password = null; $C_Password = null; $SecQ = null; $SecA = null;

在你的大 if 语句之前有一个额外的右花括号} else {（你知道我在说哪一个）

和：

139 之前的几行，缺少一个花括号。

    } else {
        echo "Error registering.";
    } // here is where it should be.                            
} else {
    echo "Username or email already entered in the database!";
}

    echo "You have been successfully registered.";

'}'

} else {
    echo "Error registering.";
}

那就是问题所在。我用引号括起来的括号。

我强烈建议您使用为 PHP 设计的 IDE（例如 Eclipse PDT）。它会准确地告诉你问题出在你的语法上。
