Serialize and unserialize a PHP object-graph to/from a JSON string-representation.
Overview
This library can serialize and unserialize a complete PHP object-graph to/from a JSON string-representation.
This library differs in a number of ways from e.g. json_encode()
, serialize()
,
var_export()
and other existing serialization libraries, in a number of important
ways.
Please see here for detailed technical background information.
The most important thing to understand, is that this library is designed to store self-contained object-graphs - it does not support shared or circular object-references. This is by design, and in-tune with good DDD design practices. An object-graph with shared or circular references cannot be stored directly as JSON, in a predictable format, primarily because the JSON data-format is a tree, not a graph.
Usage
Nothing to it.
Custom Serialization
You can define your own un/serialization functions for a specified class:
Note that this works only for concrete classes, and not for abstract classes or interfaces - serialization functions apply to precisely one class, although you can of course register the same functions to multiple classes.
Date and Time Serialization
The DateTime
and DateTimeImmutable
classes have pre-registered un/serialization
functions supporting a custom format, in which the date/time is stored in the common
ISO-8601 date/time format in the UTC timezone, along with the timezone ID - for example:
{
"#type": "DateTime",
"datetime": "1975-07-07T00:00:00Z",
"timezone": "America\/New_York"
}
