The Config Component

Introduction

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).

Caution!

The IniFileLoader parses the file contents using the :phpfunction:`parse_ini_file` function, therefore, you can only set parameters to string values. To set parameters to other data types (e.g. boolean, integer, etc), the other loaders are recommended.

Installation

You can install the component in 2 different ways:

• :doc:`Install it via Composer </components/using_components>` (symfony/config on Packagist);
• Use the official Git repository (https://github.com/symfony/Config).
