2026-04-03 12:00:21PHP

以下是一个简单的PHP实现账号切换功能的示例代码，分为登录验证和账号切换两部分：

登录验证部分

<?php
session_start();

// 模拟用户数据库
$users = [
    'user1' => ['password' => 'pass1', 'email' => 'user1@example.com'],
    'user2' => ['password' => 'pass2', 'email' => 'user2@example.com']
];

if ($_SERVER['REQUEST_METHOD'] === 'POST' && isset($_POST['login'])) {
    $username = $_POST['username'];
    $password = $_POST['password'];

    if (isset($users[$username]) && $users[$username]['password'] === $password) {
        $_SESSION['user'] = $username;
        $_SESSION['email'] = $users[$username]['email'];
        header('Location: dashboard.php');
        exit;
    } else {
        $error = "Invalid username or password";
    }
}
?>

账号切换部分

<?php
session_start();

// 检查是否已登录
if (!isset($_SESSION['user'])) {
    header('Location: login.php');
    exit;
}

// 切换账号功能
if (isset($_POST['switch_account'])) {
    session_unset();
    session_destroy();
    header('Location: login.php');
    exit;
}
?>

<!-- 显示当前用户信息 -->
<div>
    <p>Logged in as: <?php echo $_SESSION['user']; ?></p>
    <p>Email: <?php echo $_SESSION['email']; ?></p>

    <form method="post">
        <button type="submit" name="switch_account">Switch Account</button>
    </form>
</div>

多账号管理增强版

对于需要同时管理多个账号的系统，可以使用以下方法：

php实现账号切换源码

// 在登录时存储多个账号信息
$_SESSION['accounts'] = [
    'primary' => [
        'username' => 'user1',
        'email' => 'user1@example.com'
    ],
    'secondary' => [
        'username' => 'user2',
        'email' => 'user2@example.com'
    ]
];

// 切换账号功能
function switchAccount($accountType) {
    if (isset($_SESSION['accounts'][$accountType])) {
        $_SESSION['current_user'] = $_SESSION['accounts'][$accountType];
        return true;
    }
    return false;
}
