PHP框架OOP模型 [英] PHP Framework OOP model

问题描述

我认为我是经验丰富的程序PHP程序员.我已经实施了一些更大的项目.现在，我想在较小的版本上尝试OOP PHP(用于数据库导入/导出的框架+用户身份验证).由于我从未在这样的项目上尝试过OOP，所以我在对象设计方面遇到了问题.

I think I am experienced procedural PHP programmer. I've implemented a few bigger projects. Now I would like to try OOP PHP on lesser one (framework for DB import/export + user authentication). Since I've never tried OOP on such a project I have problem with object design.

我想以这种方式实现框架，我只需要创建对象的一个​​实例即可使用整个框架.我还想使代码安排得井井有条，所以我不会为所有方法/属性仅实现一个类.

I would like to implement the framework the way, I'll just need to create one instance of the object to use whole framework. I would also like to keep the code well arranged, so I won't implement only one class for all methods/properties.

我如何将一个大类分成几个较小的类，以使它们有条理(在更多的php文件中)?

How could I split one big class in to few lessers to keep them organized (in more php files)?

我认为我必须实现一个基类，然后使用其他基类对其进行扩展.但是那样，我将有许多小班，而不是大班.

I think I'll have to implement one base class and then extend it using the others. But that way I'll have many of small classes, not big one.

您将如何解决此问题?

我希望我能很好地解释问题.

I hope I explained the problem well.

感谢您的帮助.

推荐答案

我已经编写并维护了庞大的整体库多年，自从我离开该库以来，我感到更加高兴.请听我的建议:将您的应用程序分解为尽可能合理的小类.这对组织和内存使用都很有好处(一个巨大的PHP类定义会占用很多RAM，而RAM是PHP脚本中有限的资源).

I have written and maintained huge monolithic libraries for many years, and I'm way happier since I moved away from it. Take my advice: Break your application down into as small classes as possibly makes sense. It's good for organizing, as well as memory usage (a huge PHP class definition can eat up a lot of RAM, and RAM is a limited resource in a PHP script).

使用PHP 5的 自动加载 仅加载当前上下文中所需的那些类的机制.

Use PHP 5's autoloading mechanism to load only those classes thart you need in the current context.

我认为> Zend Framework 的组织和构建方式非常好.您可能想看看他们如何设计他们的类，以及他们如何在框架中组织大量功能.

I think the way Zend Framework is organized and built is quite good. You may want to take a look at how they designed their classes, and how they organized the immense amount of functionality in the framework.

关于如何组织工具以及辅助对象和库，我

As for how to organize tools and helper objects and libraries, I asked that question a few weeks back and got very good feedback. I'm still not done reading it, actually.
