我正在为我的项目构建一个用户管理系统，我想在登录用户个人资料后显示。按登录后，我应该被重定向到html page。这可行，但我不知道如何在HTML 页面中打印$_SESSION 的值，我只想在哪里或如何测试它并不重要，这样我就可以查看它是否有效并且我得到@ 987654326@。我没有找到解决方案，所以如果你能帮助我，我将不胜感激。

【问题讨论】：

html页面代码只是一个示例，没有问题。
"SELECT * FROM Users WHERE Email = '$email' AND password = '$password'" --- 请不要在现实世界的任何地方部署此代码！您以纯文本形式存储密码，并且容易受到 SQL 注入攻击。恶意用户可以轻松窃取每个人的密码。
等我做完项目再修改。

【解决方案1】：

您已将电子邮件存储在会话变量中：

$_SESSION['user'] = $email;

因此，在您的其他 HTML 页面中，您只需回显以下内容：

// myAccount.html

<?php echo "Logged in user: ".$_SESSION['user']; ?>

【讨论】：

假设 Apache 已将 .html 分配给 PHP 处理程序，否则它将是 myAccount.php
感谢您的帮助，我修改了 myAccount.php 的扩展，并添加了您提到的代码并且它工作了：D
