Philosophy

This library aims to provide a simple yet opinionated approach to configuration with the following goals:

• The configuration should operate on arrays with nested values which are easily accessible
• The configuration structure should be defined with strict schemas defining the overall structure, allowed types, and allowed values
• Schemas should be defined using a simple, fluent interface
• You should be able to add and combine schemas but never modify existing ones
• Both the configuration values and the schema should be defined and managed with PHP code
• Schemas should be immutable; they should never change once they are set
• Configuration values should never define or influence the schemas

As a result, this library will likely never support features like:

• Loading and/or exporting configuration values or schemas using YAML, XML, or other files
• Parsing configuration values from a command line or other user interface
• Dynamically changing the schema, allowed values, or default values based on other configuration values

If you need that functionality you should check out other libraries like:

• symfony/config
• symfony/options-resolver
• hassankhan/config
• consolidation/config
• laminas/laminas-config

️ Versioning

SemVer is followed closely. Minor and patch releases should not introduce breaking changes to the codebase.

Any classes or methods marked @internal are not intended for use outside this library and are subject to breaking changes at any time, so please avoid using them.

️ Maintenance & Support

When a new minor version (e.g. 1.0 -> 1.1) is released, the previous one (1.0) will continue to receive security and critical bug fixes for at least 3 months.

When a new major version is released (e.g. 1.1 -> 2.0), the previous one (1.1) will receive critical bug fixes for at least 3 months and security updates for 6 months after that new release comes out.

(This policy may change in the future and exceptions may be made on a case-by-case basis.)
