如何写好一个PHP的类?

嗯,这是一个听起来很容易,但是实际操作起来并不容易的问题。前几天和一家公司的技术负责人聊PHP面向对象在公司内的应用,他的意思是:现在很少有PHPer懂面向对象。理由很简单,没有任何一个强制性的理由使你必须使用对象化的PHP。不仅如此,你要明白一件事,面向对象的门槛,不低,但PHP的门槛,很低。

 

我承认他说的没错,就我这几年的经验来看,很多人只了解到PHP class的基本语法,但是一些核心的思想,如:类的创建原则、设计模式等,这些理论知识的运用没有一定时间的经验是没法真正明白的。我们的困扰主要在以下几个地方:

 

1. 为什么要用

 

2. 门槛很高,如何坚持下来

 

3. 使用场景

 

4. 有什么好处,我可以使用过程的方法完成的事情,为什么非要使用对象的方法

 

很遗憾,每一本将面向对象的书都有答案。可是,我们真的能明白么?

 

刚好,我们在做课程类的产品,因此,我也计划通过实践的方式给出一门主要讲解在PHP环境下如何使用面向对象的课程。我期望这门课程可以非常容易上手,因此我也把它写得非常简单:

 

1. 介绍使用的环境

 

2. 每次通过实例讲解一个小的知识点

 

3. 所有的源码发布到github分享

 

4. 类库可以被直接使用,且定期更新

 

这是一个设想,当然也需要真正的实施。
