创建一个库，该库将验证状态之间的转换，并使用它实现以下广告状态的图

               ,---------.
      |------> | Limited |
      |        `---------'
      |            |
      |            ˅
   ,-----.     ,--------.     ,----------.     ,---------.
   | New | --> | Active | --> | Outdated | --> | Removed |
   `-----'     `--------'     `----------'     `---------'
                   ˄               |
                   |---------------|

使用方法

作为项目依赖项安装

$ composer require mstovicek/state-machine

类和方法

\StateMachine\StateMachine 实现了 \StateMachine\StateMachineInterface，具有以下方法

• allowStates - 接受一个允许状态的数组作为唯一参数，仅允许此类状态之间的转换
• allowTransition - 接受两个参数 - from 和 to - 并在它们之间注册转换
• canTransit - 接受两个参数 - from 和 to - 并返回布尔值 true 如果允许此类转换，否则返回 false

开发者使用

安装依赖项

$ composer install

运行测试

$ composer tests

运行示例

$ cd examples/user-account

# install dependencies, incl. mstovicek/state-machine
$ composer install

# get current state
$ php index.php get

# set state
$ php index.php set <state>

# reset state to default
$ php index.php reset

示例输出

$ php index.php get
Current state: new

$ php index.php set active
State was set to: active

$ php index.php get
Current state: active

$ php index.php set outdated
State was set to: outdated

$ php index.php get
Current state: outdated

$ php index.php set limited
Cannot set state to limited! Check current state and allowed transitions.

$ php index.php get
Current state: outdated

$ php index.php set removed
State was set to: removed

$ php index.php get
Current state: removed
This state is terminal.

$ php index.php set active
Cannot set state to active! Check current state and allowed transitions.

$ php index.php reset
State was reset to default

$ php index.php get
