symfony/serializer

If the project contains .ddev/config.yaml, prefix every shell command with ddev (full mapping in the symfony skill's references/ddev.md). Examples target Symfony 7.4, 8.0 and newer — verify the installed version before using newer features.

When to use

You need to convert objects to/from JSON, XML, CSV, or YAML — REST APIs, queue payloads, config dumps.

Replaces

• JMS Serializer (jms/serializer)
• json_encode/json_decode + manual object hydration
• Hand-rolled toArray() / fromArray() on every DTO
