取消设置类 [英] Unset Class

问题描述

我有一个完整的表单创建系统。有很多不同的问题类型，我必须检查该人所做的答案是否正确。

i have a complete Form creation System. There are many different Question Types and I have to check if the answer which the person had made is correct.

所有类型的问题都有自己的类将总是称为ItemClass这个类在它自己的文件中。每次问一个问题，我包括文件，有这个问题：我必须检查不同类型的问题在一个PHP文件。然后出现错误 - ItemClass已经声明。

All types of Questions has its own class will is always called ItemClass and this Class is in its own File. Everytime a Question is asked I include the File and the there is that problem: I have to check different types of Questions in one PHP-File. And then there comes the error - ItemClass already declarated.

有没有任何方法来取消设置类？

Is there any method to unset a Class?

有一个美好的一天！

推荐答案

我测试了你的解决方案，最后我得到一个想法：
我将类重命名为每个类型（ynItemClass，markItemClass，...），当我需要一个项目类型时，做出以下

I tested your solutions and finally I got an Idea: I renamed the Classes to each of it's type (ynItemClass, markItemClass, ...) and when I need a Item Type a made the following

$it = $item->item_type."ItemClass";
$test = new $it($smarty);

而且有效！

美好的一天！
