Mastering the Symfony Serializer (PHP Tour slides)

The Symfony Serializer Component exists since the very beginning of Symfony 2. Years after years, it gained a lot of new features useful to transform various data formats to PHP structures and the opposite. It is also a foundation block of API Platform and a first-class citizen in FOSRest.

Let’s dive into this component. We will cover the basic concepts behind the serialization process: normalization, denormalization, encoding and decoding.

Then we will discover all the little known features of the component: JSON, XML and CSV support, file handling with “data:” URIs, serialization groups, attributes names conversion, trees support, updating existing objects, dealing with circular references.

Finally we will learn how to create custom normalizers and encoders; and how to modify the behavior of the builtin ones using composition.
