我对PHP相当陌生，我正在尝试建立一个登录系统。我正在尝试输出错误或成功消息以显示在与表单相同的页面中。我尝试使用“echo”进行测试，它可以工作，但是它会在新选项卡中显示消息。因此，我尝试将消息转换为一个变量，因此在每种情况下，该变量都会使用新消息进行更新。然后在register.php页面上，我输入一个php代码，检查消息是否为空，然后回显变量。问题是我被重定向到register.php页面，但什么也没有显示。这是我的两个文件的代码，我应该提到，注册过程确实有效，它检查电子邮件和用户名，如果没有重复的，但是它不会输出任何消息 register.php：Php 在注册表中显示消息时出现问题,php,Php,我对PHP相当陌生，我正在尝试建立一个登录系统。我正在尝试输出错误或成功消息以显示在与表单相同的页面中。我尝试使用“echo”进行测试，它可以工作，但是它会在新选项卡中显示消息。因此，我尝试将消息转换为一个变量，因此在每种情况下，该变量都会使用新消息进行更新。然后在register.php页面上，我输入一个php代码，检查消息是否为空，然后回显变量。问题是我被重定向到register.php页面，但什么也没有显示。这是我的两个文件的代码，我应该提到，注册过程确实有效，它检查电子邮件和用户名，如果
