## What it is
A Symfony PHP component that extracts information about PHP class properties (types, visibility, descriptions, accessibility) from metadata sources like reflection, PHPDoc, PhpStan types, Doctrine, and serializer groups. It provides a unified extractor interface used by frameworks and libraries such as API Platform.

## Use cases
- get property types of a php class
- extract phpdoc metadata from class properties
- introspect class properties for serialization
- determine if a property is readable or writable via getters/setters
- build api resources from doctrine entities
- read phpstan type annotations from php code

## When to choose
- you need unified property metadata across reflection, phpdoc, doctrine, and serializer sources
- you're building serialization, validation, or API tooling in PHP
- you're already in the Symfony or API Platform ecosystem

## When to avoid
- you need runtime value access rather than class definition metadata (use symfony/property-access)
- you work outside PHP
- you only need simple reflection without docblock parsing

## Facets
- artifact type: library
- maturity: stable
- function: serialization, developer-tools, type-system
- domain: developer-tools, web-development, backend
- platform: php, cross-platform
- tags: symfony-component, phpdoc, reflection, doctrine, property-metadata, type-extraction
