An Action system for Action-Domain-Responder.

This package is installable and PSR-4 autoloadable via Composer as arbiter/arbiter.

Alternatively, download a release or clone this repository, then map the Arbiter\ namespace to the package src/ directory.

This package requires PHP 5.5 or later; it has been tested on PHP 5.6, PHP 7, and HHVM. You should use the latest available version of PHP as a matter of principle.

To run the tests, issue composer install to install the test dependencies, then issue phpunit.

An Action value object is composed of three elements:

  • an $input callable: this collects input from the incoming ServerRequestInterface and converts it to an array of parameters suitable for call_user_func_array();

  • a $domain callable: this is invoked via call_user_func_array() using the array of parameters provided by the $input callable; and

  • a $responder callable: this is invoked with the incoming ServerRequestInterface, the outgoing ResponseInterface, and the result (or "payload") returned by the $domain callable.

Call the ActionHandler handle() method with the Action, a ServerRequestInterface, and a ResponseInterface. The ActionHandler then acts as a mediator to direct the interaction between the three callables, and returns a modified ResponseInterface.
