php - PHP 从另一个 php 文件调用变量

问题描述

我有 3 个 php 文件。test.php 用于创建电子邮件的用户表单。process.php 用于处理验证和保存输入。最后一个registration2.php 是第二个页面，用上一节的输入来欢迎用户。我正在尝试将变量调用到此页面上，但似乎变量未保存或为空。我似乎无法弄清楚为什么？

测试.php

    <?php if(!isset($firstName)){
    $firstName='';
}if(!isset($lastName)){
    $lastName='';
}if(!isset($userName)){
    $userName='';
}if(!isset($password)){
    $password='';
}if(!isset($valPassword)){
    $valPassword='';
}
?>
