The Config Component

Edit this page

Warning: You are browsing the documentation for Symfony 3.2, which is no longer maintained.

Read the updated version of this page for Symfony 6.2 (the current stable version).

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/config on 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.
