PHP设计模式-Builder 建造者模式

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
 *
