## 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。

## 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

```
