整理一下自己的學(xué)習(xí)Aaron Saray 寫的PHP設(shè)計(jì)模式一些demo和自己的理解。大佬看完如果發(fā)現(xiàn)鄙人理解有誤請(qǐng)立即指出，感謝拍磚，跪求鞭打

/**
 * Builder  建造者模式
 * -------------------------------------
 * ** 來自說明 **
 *
 * 建造者設(shè)計(jì)模式的母的是消除其他對(duì)象的復(fù)雜創(chuàng)建過程，
 * 使用建造者設(shè)計(jì)模式不僅是最佳的做法
 * 而且在某個(gè)對(duì)象的構(gòu)造和配置方法改變時(shí)盡可能地減少重復(fù)的代碼
 * 
 * ===================================== 
 * ** 應(yīng)用場(chǎng)景 **
 *
 * 數(shù)據(jù)庫接口類 | 優(yōu)化基類
