我有一个数据库,人们可以同时成为雇员、客户和公司成员。 我的行政管理系统允许我编辑<代码>Person 、Employee、Customer和-Member上独立页的物体。
现在,我能够打电话到
我确实理解,雇员、客户和成员在没有个人的情况下就存在,因此,我想我应当创建一个新的类别:
如同继承问题一样。 您有<代码>Person,但可以以更具体的措辞描述此人,例如。 Employee or Customer.
通常以目标为导向的方案拟订工作,你从基类开始(例如,<代码>Person/code>,然后在扩大子类时添加特性。 因此,<代码>Person可有名称、。 雇员人数() 客户。
What you could do is implement a decorator pattern, and just keep building on your Person class. I m not sure how you re currently building people s profiles in your current application, but it would look something as follows in pseudo code:
<?php
$id = intval($_GET[ person_id ]);
$employee = new Employee(new Person($id));
届时将转至<代码>。 雇员()类别与雇员特有的额外财产和方法相关。
