# PHP 设计模式系列 —— 建造者模式（Builder）
2+
## 1、模式定义
3+
建造者模式将一个复杂的对象的构建与它的表示分离，使得同样的构建过程可以创建不同的表示。
4+
5+
## 2、问题引出
6+
假设我们有个生产车的工厂，可以制造各种车，比如自行车、汽车、卡车等等，如果每辆车都是从头到尾按部就班地造，必然效率低下。
7+
8+
## 3、解决办法
9+
我们可以试着将车的组装和零部件生产分离开来：让一个类似“导演”的角色负责车子组装，而具体造什么样的车需要什么样的零部件让具体的“构造者”去实现，“导演”知道什么样的车怎么造，需要的零部件则让“构造者”去建造，何时完成由“导演”来控制并最终返回给客户端。
10+
11+
## 4、UML类图
12+
![Builder-UML.png](/static/images/Builder-UML.png)
13+
14+
## 5、总结
15+
建造者模式和抽象工厂模式很像，总体上，建造者模式仅仅只比抽象工厂模式多了一个“导演类”的角色。与抽象工厂模式相比，建造者模式一般用来创建更为复杂的对象，因为对象的创建过程更为复杂，因此将对象的创建过程独立出来组成一个新的类 —— 导演类。也就是说，抽像工厂模式是将对象的全部创建过程封装在工厂类中，由工厂类向客户端提供最终的产品；而建造者模式中，建造者类一般只提供产品类中各个组件的建造，而将完整建造过程交付给导演类。由导演类负责将各个组件按照特定的规则组建为产品，然后将组建好的产品交付给客户端。
