The Config Component
The Config component provides several classes to help you find, load, combine, autofill and validate configuration values of any kind, whatever their source may be (YAML, XML, INI files, or for instance a database).
Installation
You can install the component in 2 different ways:
- Install it via Composer (
symfony/configon Packagist); - Use the official Git repository (https://github.com/symfony/config).
Then, require the vendor/autoload.php file to enable the autoloading mechanism
provided by Composer. Otherwise, your application won't be able to find the classes
of this Symfony component.
