我创建了一个名为 classperson.php 的文件，在其中声明了所有变量。

<?php
class person1
{
    var $location;
    var $effective;
    var $training;
    var $treated;
    var $effort;
    var $information;
    var $recognition;
    var $valued;
    var $supervisor;
    var $informed;
    var $job;
    var $treats;
    var $satisfy;
    var $workgroup;
    var $utc;
    var $skills;

    function set_location($new_location)
    {
        $this->location=$new_location;
    }
    function get_location()
    {
        return $this->location;
    }


    function set_effective($new_effective)
    {
        $this->effective=$new_effective;
    }
    function get_effective()
    {
        return $this->effective;

后来我在 oopossurvey.php 中包含了这个文件。这是一个有 5 页的表格

看看代码

我的问题是，这是在 php 中使用面向对象概念创建或创建表单的正确方法吗？或者我应该创建更多对象或进行任何更改？

我试图在所有页面上包含文件 classperson.php，但是当我使用下一个按钮时出现错误。

提前致谢

首先，您所说的“页面”仅在客户端使用，但对于 PHP，它是单个脚本。因此，例如多次执行 session_start() 是没有意义的，因为每次向服务器发送数据时，脚本都会再次从头开始运行。当它到达当前页面的末尾时，它也不会停止运行。

其次，这种通过会话变量确定调查步骤的想法本身有点生疏，并且没有正确实施。我很确定它不起作用（尽管我没有运行代码）。在会话中存储变量并没有什么不好，但我的建议是你应该以某种方式重新考虑逻辑。例如，您可以在每个表单中使用一些隐藏的输入来检查用户是哪个步骤的调查，并且在 PHP 文件中有一些switch{}()用于每个页面的案例。

第三，不要这么混淆，你应该把逻辑和表现分开。我的意思是 - 对所有表单使用单独的文件，并使用单独的文件接受来自用户的数据，将其写下来（如您的示例 - 在会话中），然后选择接下来要显示的页面。这样，您将更容易定位错误，并且它会更多地在您的脑海中安定下来。

至于你关于 PHP 中使用的类的问题：通常你应该只包含一次类，不需要重新包含它，例如在这个文件中你将处理所有逻辑。然后，您可以创建该类的实例并使用它。无论如何，我有一种感觉，你有些着急，而且在我看来，你现在开始使用 OOP 技术还为时过早——最好是一步一步来。尝试让这个脚本在没有类的情况下工作。当它可以工作时，将逻辑提取到一个类中。这样你会更好地理解一切:)
