Question

有人能告诉我为什么PHP会给我这个错误吗？：

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）

我似乎无法找到问题

代码：

<?php

if ($isLoggedin === false) {

                                include("form.php");


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

Answer 1

在你的大if语句的} else {之前有一个额外的大括号（你知道我在说什么）

和

在139之前的几行中，有一个缺少大括号。

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

Answer 2

    echo "You have been successfully registered.";

'}'

} else {
    echo "Error registering.";
}

这就是问题所在。我引用的括号。

我强烈建议您使用专为PHP设计的IDE（例如Eclipse PDT）。它会告诉你问题与你的语法有关。
