[](#phpchain-)

Set of classes that help to create chains of steps to minimize clutter in domain logic.

Install
-------

[](#install)

`composer require aambr/phpchain`

Quick start
-----------

[](#quick-start)

```
$dispatcher = new ChainDispatcher($dependencyInjectionContainer);
$dispatcher->chain('user.register')->define([
  'Steps\CreateUserStep', Steps\CreateProfileStep::class, 'sendWelcomeEmail'
]); // all of these will be resolved by dependency container unless
    // there is a concrete ChainStep object ready

$dispatcher->chain('user.register')->dispatch()->execute(new \ArrayObject([
  'username' => 'valid-username',
  'email' => 'valid@email.com'
]));
```

`ChainDispatcher` accepts any depenendecy injection container which extends `\ArrayObject` to resolve each step depenendecy.

Divide and conquer
------------------

[](#divide-and-conquer)

The goal is to devide complex domain logic into individual steps that can be reused in future processes. Create your own steps by inheriting `ChainStep` and implement logic in `process(\ArrayObject $input)`.

Share variables between steps
-----------------------------

[](#share-variables-between-steps)

Steps can share variables between each other by altering `$input` keys, which is possible because we are passing `\ArrayObject` instance reference instead an array which is passed by value. For example `CreateUserStep` after successful action can set `$input['user'] = $createdUser`, which then can be used by `sendWelcomeEmail`.
