Dot Access Configuration

Given a deep data structure representing a configuration, access configuration by dot notation.

This library combines dflydev/dot-access-data and dflydev/placeholder-resolver to provide a complete configuration solution.

Requirements

• PHP (5.3+)
• dflydev/dot-access-data (^3)
• dflydev/placeholder-resolver (1.x)
• symfony/yaml (>2,<2.2) (suggested)

Usage

Generally one will use an implementation of ConfigurationBuilderInterface to build ConfigurationInterface instances. For example, to build a Configuration out of a YAML file, one would use the YamlFileConfigurationBuilder:

use Dflydev\DotAccessConfiguration\YamlFileConfigurationBuilder;

$configurationBuilder = new YamlFileConfigurationBuilder('config/config.yml');
$configuration = $configurationBuilder->build();

Once created, the Configuration instance behaves similarly to a Data instance from dflydev/dot-access-data.

$configuration->set('a.b.c', 'ABC');
$configuration->get('a.b.c');
$configuration->set('a.b.e', array('A', 'B', 'C'));
$configuration->append('a.b.e', 'D');

Custom Configurations

Configuration Builders use Configuration Factories and Placeholder Resolver Factories behind the scenes in order to build a working configuration.

Under normal circumstances one should not need to do anything with the Placeholder Resolver Factory. However, one may wish to extend the default Configuration class or use an entirely different implementation altogether.

In order to build instances of custom ConfigurationInterface implementations with the standard builders, one would need to implement ConfigurationFactoryInterface and inject it into any ConfigurationBuilderInterface.

If a Configuration is declared as follows:

namespace MyProject;

use Dflydev\DotAccessConfiguration\Configuration;

class MyConf extends Configuration
{
    public function someSpecialMethod()
    {
        // Whatever you want here.
    }
}

Create the following factory:

namespace MyProject;

use Dflydev\DotAccessConfiguration\ConfigurationFactoryInterface;

class MyConfFactory implements ConfigurationFactoryInterface
{
    /**
     * {@inheritdocs}
     */
    public function create()
    {
        return new MyConf;
    }
}

To use the factory with any builder, inject it as follows:

use Dflydev\DotAccessConfiguration\YamlFileConfigurationBuilder;
use MyProject\MyConfFactory;

$configurationBuilder = new YamlFileConfigurationBuilder('config/config.yml');

// Inject your custom Configuration Factory
$configurationBuilder->setConfigurationFactory(new MyConfFactory);

// Will now build instances of MyConfFactory instead of
// the standard Configuration implementation.
$configuration = $configurationBuilder->build();
