Waffle Config Component

A robust configuration management library for PHP, supporting YAML files and environment variable substitution.

📦 Installation

composer require waffle-commons/config

🚀 Usage

Basic Usage

use Waffle\Commons\Config\Config;

// Initialize Config with the path to your configuration directory and current environment
$config = new Config('/path/to/config/dir', 'prod');

// Retrieve a string value
$dbHost = $config->getString('database.host');

// Retrieve an integer with a default value
$port = $config->getInt('database.port', 3306);

// Retrieve a boolean
$debug = $config->getBool('app.debug', false);

Environment Variables

You can reference environment variables in your YAML files using the %env(VAR_NAME)% syntax:

# config/app.yaml
database:
  host: '%env(DB_HOST)%'
  password: '%env(DB_PASSWORD)%'

Environment Specifics

The loader automatically merges app.yaml with app_{env}.yaml. For example, if your environment is prod, it will load app.yaml and then override values with app_prod.yaml.

Testing

To run the tests, use the following command:

composer tests
