A PHP experiment library inspired by Github's own Scientist.

Scientist is an experimentation framework for PHP that will allow you to refactor and improve upon existing code in a live environment, without incurring risk or breakages.

Simply define an experiment, sit back, and let the results flow in.

<?php

// We need a Laboratory to do science.
$experiment = (new Scientist\Laboratory)

    // Define an experiment with a name.
    ->experiment('experiment title')
    
    // Set a callback containing our control code.
    ->control($controlCallback)
    
    // Set a callback containing our trial code.
    ->trial('trial name', $trialCallback);

// Run the experiment, receiving the control return value.
$value = $experiment->run();

A more detailed description, and full documentation is available.

Users of scientist contribute a variety of resources to enhance the functionality of the application.

Journals allow experiment data to be sent to data stores for later inspection.

• PSR-3 / Monolog by Nikko Bautista. - Write experiments to any PSR-3 compatible logger.

Bridges allow for Scientist to be used seamlessly with other frameworks and libraries.

• Laravel by Dayle Rees - Use Scientist with the Laravel PHP framework.
• Symfony by Dan Hanly - Use Scientist with the Symfony PHP framework.
• Silex by Mauro Moreno - Use Scientist with the Silex micro-framework.

Matchers allow for complex types to be matched.

• Utility Matchers by Dan Hanly

Interfaces allow for experiment data to be viewed in a clear way.
