Serializing JSON Using Streams

Symfony can encode PHP data structures to JSON streams and decode JSON streams

back into PHP data structures.

To do this, it relies on the :doc:`JsonStreamer component </serializer/streaming_json>`,

which is designed for high efficiency and can process large JSON data incrementally,

without needing to load the entire content into memory.

When deciding between the Serializer component and the JsonStreamer component,

consider the following:

* **Serializer Component**: Best suited for use cases that require flexibility,

such as dynamically manipulating object structures using normalizers and

denormalizers, or handling complex objects with multiple serialization

formats. It also supports output formats beyond JSON (including your own

custom ones).

* **JsonStreamer Component**: Best suited for simple objects and scenarios that

demand high performance and low memory usage. It's particularly effective

for processing very large JSON datasets or when streaming JSON in real-time

without loading the entire dataset into memory.

The choice depends on your specific use case. The JsonStreamer component is

tailored for performance and memory efficiency, whereas the Serializer

component provides greater flexibility and broader format support.
