Dikki Config

Disclosure: The documentation on this page was written with Claude AI.

Dikki Config is a PHP library that allows you to create and manage configuration files for your PHP applications. It supports multiple file formats including PHP arrays, .env files, JSON, YAML, INI, and Neon. This library provides a unified interface to access configuration values regardless of the underlying file format.

Supported Parsers

• PHP Array (Dikki\Config\PhpArrayParser)
• JSON (Dikki\Config\JsonParser)
• YAML (Dikki\Config\YamlParser)
• INI (Dikki\Config\IniParser)
• Neon (Dikki\Config\NeonParser)
• DotEnv (Dikki\Config\DotEnvParser)

Installation

To install Dikki Config, use Composer:

composer require dikki/config

Usage

Multiple Config File Types

If you are using more than one type of configuration file, you can use the ConfigFetcher class to fetch and merge configurations from all supported file types.

Example of using ConfigFetcher Class

use Dikki\Config\ConfigFetcher;

$configFetcher = new ConfigFetcher(__DIR__ . '/config');

// Fetch all configurations
$config = $configFetcher->fetch();

// Get a specific configuration value using dot notation
echo $configFetcher->get('app.timezone');

Individual Config File Types

If you are using only one type of configuration file, you can use the Config class with the appropriate parser.

Create a Config File or Folder

First, ensure that you have a config folder in your project. Add all your config files in this folder.

Example

use Dikki\Config\Config;
use Dikki\Config\YamlParser;

// Create an instance of the Config class
$config = new Config(new YamlParser(__DIR__ . '/config')); # pass either single file path or whole directory

// Get a configuration value (dot notation is supported)
echo $config->get('app.timezone');

OUTPUT: UTC

More Details

ConfigFetcher Class

The ConfigFetcher class is designed to recursively search for and parse all supported configuration file formats within a given directory.

Constructor

public function __construct(string $path)

• path: The path to the directory containing configuration files.

Methods

• fetch(): Fetch and parse all supported config files.
• getFiles(string $dir): Recursively get all files from the given directory.
• mergeConfigs(array $baseConfig, array $newConfig): Merge two configuration arrays, preserving nested keys.
• get(string $key, mixed $default = null): Get a specific configuration value by key using dot notation.

Config Class

The Config class takes an instance of a class implementing ConfigInterface and delegates the get() method to it.

Constructor

public function __construct(ConfigInterface $parser)

• parser: An instance of a class implementing ConfigInterface.

Methods

• get(string $key, mixed $default = null): Get a value from the config array using dot notation.
• getAll(): Get all configuration values.
• parse(): Parse the configuration file(s) and return an array.

Parser Classes

Each parser class implements the ConfigInterface and provides methods to parse specific file formats.

Common Methods

• parse(): Parse the configuration file(s) and return an array.
• get(string $key, mixed $default = null): Get a value from the config array using dot notation.

DotEnvParser

Parses .env files.

IniParser

Parses INI files.

JsonParser

Parses JSON files.

NeonParser

Parses Neon files.

PhpArrayParser

Parses PHP array files.

YamlParser

Parses YAML files.

Testing

To test the functionality of the Dikki Config library, you can use the provided test cases coded using Nette Tester.

use Dikki\Config\Config;
use Dikki\Config\ConfigFetcher;
use Dikki\Config\DotEnvParser;
use Dikki\Config\IniParser;
use Dikki\Config\JsonParser;
use Dikki\Config\NeonParser;
use Dikki\Config\PhpArrayParser;
use Dikki\Config\YamlParser;
use Tester\Assert;

require __DIR__ . '/vendor/autoload.php';

Tester\Environment::setup();

$configDir = __DIR__ . '/config';

$configFetcher = new ConfigFetcher($configDir);
$dotenvConfig = new Config(new DotEnvParser($configDir . '/.env'));
$iniConfig = new Config(new IniParser($configDir . '/iniconfig.ini'));
$jsonConfig = new Config(new JsonParser($configDir . '/jsonconfig.json'));
$neonConfig = new Config(new NeonParser($configDir . '/neonconfig.neon'));
$phpConfig = new Config(new PhpArrayParser($configDir . '/phpconfig.php'));
$yamlConfig = new Config(new YamlParser($configDir . '/yamlconfig.yaml'));

// Test individual parsers
Assert::equal($dotenvConfig->get('APP_NAME'), "Sample App");
Assert::equal($iniConfig->get('app.url'), "https://example.com");
Assert::equal($jsonConfig->get('app.author'), "Naman");
Assert::equal($neonConfig->get('app.debug'), false);
Assert::equal($phpConfig->get('app.timezone'), "Asia/Kolkata");
Assert::equal($yamlConfig->get('app.theme'), "Default");

// Test ConfigFetcher

Assert::equal($configFetcher->get('app.debug'), false);
Assert::equal($configFetcher->get('app.timezone'), "Asia/Kolkata");
Assert::equal($configFetcher->get('app.theme'), "Default");
