The Config Component

Edit this page

The Config component provides utilities to define and manage the configuration options of PHP applications. It allows you to:

  • Define a configuration structure, its validation rules, default values and documentation;
  • Support different configuration formats (YAML, XML, INI, etc.);
  • Merge multiple configurations from different sources into a single configuration.

Note

You don't have to use this component to configure Symfony applications. Instead, read the docs about how to configure Symfony applications.

Installation

1
$ composer require symfony/config

Note

If you install this component outside of a Symfony application, you must require the vendor/autoload.php file in your code to enable the class autoloading mechanism provided by Composer. Read this article for more details.
