The Symfony Config component is a PHP library for finding, loading, combining, autofilling, and validating configuration values from any source, such as YAML, XML, or INI files. It lets developers define configuration structures with validation rules and defaults, and merge configurations from multiple sources into one.

Use cases

• load and validate yaml config files in php
• merge configuration from multiple sources
• define config schema with defaults and validation rules
• parse xml and ini configuration in php
• build friendly configuration for a symfony bundle
• cache configuration based on resource changes

When to choose

• you need structured, validated application configuration in PHP
• you are building a Symfony bundle with user-facing configuration
• you need to combine config from YAML, XML, INI, or databases

When to avoid

• your project uses a language other than PHP
• you only need simple key-value config without validation or merging
• you want a full framework rather than a single component
