A finite state machine for php

Requirements and installation

• PHP 7.1+

Usage

State definition

Simple state definition

$state = new NormalState('state');

$state
  ->event('publish', 'published')
  ->trigger('beforePublish', function() { /* exec before $state->publish() run */ })
  ->trigger('onExit', function() { return /* will be executed when leaving this state */; });
  
$state->publish(); // return 'published'

Class based state definition

// file SimpleState.php
class SimpleState implements StateInterface {
  
  // public method it is event
  public function publish()
  {
    return 'published';
  }
  
  // before<*> or after<*> it is triggers
  // runs before and after event execute
  public function beforePublish()
  {
    return true;
  }
  
  // This is trigger like an 'onExit', 'onReset'
  public function onExit()
  {
    return true;
  }
}

$state = new SimpleState();
$state->publish(); // return 'published'
