## What it is
jms/serializer is a PHP library for serializing and deserializing data of any complexity, supporting JSON and XML formats. It offers configurable metadata (XML, YAML, annotations), exclusion strategies, circular reference handling, and Doctrine ORM integration, with a Symfony bundle available.

## Use cases
- serialize PHP objects to JSON for API responses
- deserialize JSON payloads into typed PHP objects
- convert objects to XML and back
- control API output with exclusion strategies and versioning
- map Doctrine entities to JSON/XML representations

## When to choose
- you need robust object (de-)serialization in PHP with fine-grained output control
- you work with Symfony and want a mature serializer bundle
- you need to handle circular references or complex object graphs
- you want annotation, XML, or YAML-based mapping configuration

## When to avoid
- you only need simple json_encode/json_decode without object mapping
- you use a framework with a built-in serializer that suffices
- you need formats beyond JSON and XML

## Facets
- artifact type: library
- maturity: stable
- function: serialization, json
- domain: web-development, backend, developer-tools
- platform: php
- tags: jms-serializer, symfony-bundle, doctrine-integration, object-mapping, api-versioning, xml
