## What it is
A standalone Symfony PHP component that improves on array_replace for handling configuration options. It provides required options, defaults, type and value validation, and normalization for option arrays.

## Use cases
- resolve options arrays with defaults in php
- validate configuration options types and values
- require certain options to be passed
- normalize option values before use
- replace boilerplate array_merge config handling
- define nested or prototype options

## When to choose
- you build PHP libraries or classes accepting an options array
- you want declarative defaults, required options, and validation instead of manual isset checks
- you already use Symfony components

## When to avoid
- your project is not PHP
- you only need simple array merging with no validation
- you prefer constructor promotion or DTO-based configuration

## Facets
- artifact type: library
- maturity: stable
- function: configuration-management, developer-tools
- domain: developer-tools, web-development, backend
- platform: php, cross-platform
- tags: options-resolver, array-replace, defaults, validation, symfony-component, composer
