Learn data structure use PHP Language.
This is shame that I have not learn in university and senior middle school. But I got PHP engineer work several years. Until the thirties, I start to learn the "data structure".
The goal of this repository is learnning. Most of code of this repository would not use in any projects, so I will try to implement function first then optimize code follow the code style.
English write bad, I try my best.
用PHP语言学习数据结构。
说起来让人汗颜，身为没有接受过高中和大学教育的草根PHP工程师，到了而立之年才开始学习数据结构。
该项目的目的就是学习，可能其中大部分代码不会用在实际的工程中，所以我会先努力去实现功能，之后再按照工程标准优化代码。
英文不好，我努力说。
