Example of using the containers in Symphony

<?php

// Usage of Core

namespace SymphonyCMS;

class MyService
{
    /**
     * Constructor expects a tailored subset of core components
     * @param Core $core
     */

 * We can create a service that uses a tailored subset of services and/or values from the core
 * container.

        'list',
        'of',
        'required',
        'services'

}

/**
 * Or we can create a service that takes the entire container.
 */

/**
 * Or we can create a service that takes a single dependency
 */

/**
 * For backwards compatibility with Symphony CMS, we define it a little differently
 */
class Symphony extends Core {}

// Inside Symphony, we will declare all the dependencies as such
Symphony::set('Log', new Log(...));

// And call them as we currently do
Symphony::Log()
