我正在尝试制作简单的联系表格，我有两个文件，contact.php和index.php
我希望将几个选项出现在我的index.php文件中"查询类型"中的"我在contact.php文件中放入的那些选项：
<?php
class Contact{
public static $types = array(
1 => 'Product enquiry',
2 => 'Billing enquiry',
3 => 'Support enquiry'
);
}我还包括contact.php in index.php文件：
<?php require_once('file:///D:/Simple%20Contact%20Form/Liberay/Contact.php'); ?>但是经过大量尝试，我看不到下拉字段的任何选项，所以可能是连接的东西吗？当我尝试使用PHP代码时，我是否应该将其放在XAMPP的本地服务器中？
这是index.php的完整代码：
<?php require_once('file:///D:/Simple%20Contact%20Form/Liberay/Contact.php'); ?>

如果您正在使用XAMPP，则将所有文件放在 htdocs 文件夹下。您已经提到
<?php require_once('file:///D:/Simple%20Contact%20Form/Liberay/Contact.php'); ?>
- 指的是本地文件路径。
