> 一个php技术栈后端猿的知识储备大纲
## 前言
为什么把php,mysql,redis放在前三位？因为php/mysql/redis基础是一个当代phper的根基。
## 备注

## 测试用例
### 设计模式
运行脚本： php patterns/[文件夹名称]/test.php
```
例如,
测试责任链模式： 运行 php patterns/chainOfResponsibility/test.php
运行结果：
请求5850c8354b298: 令牌校验通过～
请求5850c8354b298: 请求频率校验通过～
请求5850c8354b298: 参数校验通过～
请求5850c8354b298: 签名校验通过～
请求5850c8354b298: 权限校验通过～
```
### 算法
运行脚本： php algorithm/test.php [算法名称｜空获取列表]
```
例如,
测试冒泡排序： 运行 php algorithm/test.php bubble
运行结果：
==========================冒泡排序=========================
Array
(
[0] => 11
[1] => 67
[2] => 3
[3] => 121
[4] => 71
[5] => 6
[6] => 100
[7] => 45
[8] => 2
)
=========上为初始值==================下为排序后值=============
Array
(
[0] => 2
[1] => 3
[2] => 6
[3] => 11
[4] => 45
[5] => 67
[6] => 71
[7] => 100
[8] => 121
)
```
### 常见redis运用实现
运行脚本： php redis/test.php [名称｜空获取列表]
```
例如,
测试悲观锁： 运行 php redis/test.php p-lock
运行结果：
执行count加1操作～
count值为：1
```
