Injectable Configs

All framework components talk to config files though the set of config objects. Framework bundle provides ability to automatically route and populate such objects using contextual injections by ConfigFactory.

Create configuration

To create new config object, place file in app/config (sub-dirs are allowed), example "my-config.php":

php
return [
    'option' => 'value'
];

Config data can now be read using ConfiguratorInterface:

php
public function indexAction(ConfiguratorInterface $configurator)
{
    dump($configurator->getConfig('my-config')['option']);
}

ConfigObject

In order to properly represent configuration in the container create class extends InjectableConfig:

php
class MyConfig extends InjectableConfig
{
    const CONFIG = 'my-config';

    //Default config values (docs) if any
    protected $config = [
        'option' => null
    ];

    /**
     * @return string
     */
    public function getOption(): string
    {
        return $this->config['option'];
    }
}

Config object can be used immediately as injection:

php
public function indexAction(MyConfig $config, ConfiguratorInterface $configurator)
{
    dump($config->getOption());
    dump($config->getOption() === $configurator->getConfig('my-config')['option']);
}

Config objects can be used to properly handle legacy configuration formats:

php
public function getOption()
{
    if (!empty($this->config['new-option'])) {
        //Some new feature
        return $this->config['new-option'];
    }

    return $this->config['option'];
}

All created configs are cached in ConfigFactory, use flushCache() to reset such cache.
