phpdesignpattern's Introduction

PHP设计模式

面向对象的目标
  • 高内聚，低耦合
面向对象设计的基本原则
  1. 单一职责：一个类只做一件事
  2. 开闭原则：对扩展开放对修改关闭
  3. 里氏替换：子类必须能替换所有父类的使用
  4. 依赖倒置：设计依赖于抽象而不是实现
  5. 最少知识：对象应当尽可能少的去了解其他对象
  6. 接口隔离：接口倾向于小而多
  7. 组合优先：优先使用类的组合而不是继承

抽象类和接口的使用

  • 当类中有共同的行为或属性时,可以考虑使用 abstract calss
  • 当类别中有共同的操作界面,但是在实现上有所差别,可以考虑使用 interface
