整理一下自己的学习Aaron Saray 写的PHP设计模式一些demo和自己的理解。大佬看完如果发现鄙人理解有误请立即指出,感谢拍砖,跪求鞭打
/**
* Builder 建造者模式
* -------------------------------------
* ** 来自说明 **
*
* 建造者设计模式的母的是消除其他对象的复杂创建过程,
* 使用建造者设计模式不仅是最佳的做法
* 而且在某个对象的构造和配置方法改变时尽可能地减少重复的代码
*
* =====================================
* ** 应用场景 **
*
* 数据库接口类 | 优化基类
*

// 但是爱折腾的你从来不会放弃任何机会,自从学习了建造者模式的你 总有种蠢蠢欲动,于是乎就有了下面的类
