The Symfony Serializer component transforms data structures, including object graphs, into array structures or formats like XML and JSON, and back. It uses a flexible system of normalizers and encoders and is commonly used for building APIs and integrating with third-party services.
Use cases
- serialize PHP objects to JSON for API responses
- deserialize incoming JSON request payloads into PHP objects
- convert object graphs to XML
- map arrays to typed PHP objects
- ignore or rename properties during serialization
- handle circular references when serializing object graphs
When to choose
- you are building a PHP or Symfony application that needs JSON/XML conversion
- you need configurable object-to-array mapping with normalizers
- you want battle-tested serialization used by Drupal, Shopware, API Platform, and others
When to avoid
- you are not working in PHP
- you need extremely high-performance binary serialization formats like protobuf or msgpack
- your framework already provides an equivalent serializer you already use
