The Config Component
Warning: You are browsing the documentation for Symfony 5.x, which is no longer maintained.
Read the updated version of this page for Symfony 7.2 (the current stable version).
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.
