Konfig

Konfig is a simple configuration file loader library that supports INI, JSON, NEON, PHP, TOML, XML and YML files.

Requirements

Konfig requires PHP 5.4+, and suggests using Yosymfony Toml Parser, Piwik INI Parser, Nette NEON and Spyc YAML Library.

Installation

The supported way of installing Konfig is via Composer.

$ composer require kodeburner/konfig

Usage

Konfig is designed to be very simple, lightweight and straightforward to use. All you can do with it is load, get, and set.

Loading files

The Konfig object can be created via the factory method load(), or by direct instantiation:

use Exen\Konfig\Konfig;

// Load a single file
$konf = Konfig::load('konfig.json');
$konf = new Konfig('konfig.json');

// Load values from multiple files
$konf = new Konfig(['konfig.json', 'konfig.xml']);

// Load all supported files in a directory
$konf = new Konfig(__DIR__ . '/konfig');

// Load values from optional files
$konf = new Konfig(['konfig.dist.json', '?konfig.json']);

Files are parsed and loaded depending on the file extension. Note that when loading multiple files, entries with duplicate keys will take on the value from the last loaded file.

When loading a directory, the path is globed and files are loaded in by name alphabetically.

Getting values

Getting values can be done in three ways. One, by using the get() method:

// Get value using key
$debug = $konf->get('debug');

// Get value using nested key
$secret = $konf->get('security.secret');

// Get a value with a fallback
$ttl = $konf->get('app.timeout', 3000);

The second method, is by using it like an array:

// Get value using a simple key
$debug = $konf['debug'];

// Get value using a nested key
$secret = $konf['security.secret'];

// Get nested value like you would from a nested array
$secret = $konf['security']['secret'];

The third method, is by using the all() method:

// Get all values
$data = $konf->all();

Setting values

Although Konfig supports setting values via set() or, via the array syntax, any changes made this way are NOT reflected back to the source files. By design, if you need to make changes to your configuration files, you have to do it manually.

$konf = Konfig::load('konfig.json');

// Sample value from our konfig file
assert($konf['secret'] == '123');

// Update konfig value to something else
$konf['secret'] = '456';

// Reload the file
$konf = Konfig::load('konfig.json');

// Same value as before
assert($konf['secret'] == '123');

// This will fail
assert($konf['secret'] == '456');

Using with default values

Sometimes in your own projects you may want to use Konfig for storing application settings, without needing file I/O. You can do this by extending the AbstractKonfig class and populating the getDefaults() method:

class MyKonfig extends AbstractKonfig
{
    protected function getDefaults()
    {
        return array(
            'host' => 'localhost',
            'port'    => 80,
            'servers' => array(
                'host1',
                'host2',
                'host3'
            ),
            'application' => array(
                'name'   => 'configuration',
                'secret' => 'secretValue'
            )
        );
    }
}
