Simple-Serializer

Introduction

Simple-Serializer allows you to serialize your objects into a requested output format such as JSON. The library is written to work with DTO objects in the REST services.

Built-in features include:

• (de-)serialize object graphs
• supports boolean, integer, double, DateTime<format>, array, T, array<T>, null types, where "T" - is some PHP object.
• configurable via YAML
• three unserialize mode (non-strict, medium strict, strict)

Unserialize mode: Non-Strict mode - serializer does not check incoming parameters Medium Strict - serializer extra check incoming parameters and if they exist throw InvalidArgumentException Strict - serializer extra check incoming parameters completely as expected if there are extra arguments or missing some, it throws an exception.

Some Restrictions:

• object must have configuration for serialize/unserialize

Possible TODO list:

• (de-)serialize object graphs of any complexity including circular references
• configurable via PHP, XML, or annotations
• custom integrates with Doctrine ORM, et. al.

It should be noted that Simple-Serializer is realy simple library with minimum configuration, but it provides wide opportunity for create REST API.

Installation

To install Simple-Serializer with Composer just add the following to your composer.json file:

    // composer.json
    {
        // ...
        require: {
            // ...
            "opensoft/simple-serializer": "dev-master"
        }
    }

Then, you can install the new dependencies by running Composer's update command from the directory where your composer.json file is located:

$ php composer.phar update

Configuration

MyBundle\Resources\config\serializer\ClassName.yml
    Fully\Qualified\ClassName:
        properties:
            some-property:
                expose: true
                type: string
                serialized_name: foo
                since_version: 1.0
                until_version: 2.0
                groups: ['get','patch']

• expose
• true
• false (default)
• type
• integer
• boolean
• double
• string
• array
• T - fully qualified class name
• array<T>
• DateTime
• DateTime<format>
• format could be name of DateTime constant (COOKIE, ISO8601), string or empty (default format is ISO8601)
• serialized_name
• default value is equal name property
• since_version
• string
• until_version
• string
• groups
• array
• null_skipped
• true
• false (default)

Serializing Objects

Most common usage is probably to serialize objects. This can be achieved very easily:

    <?php
    //get Serializer
    $serializer = $this->getSerializer();
    $string = $serializer->serialize($object);
    //Serialize array of the objects
    $string = $serializer->serialize(array($object));
    //Serialize specific groups
    $serializer->setGroups(array('get'));
    $string = $serializer->serialize($object);
    //Serialize specific version
    $serializer->setVersion('1.0');
    $string = $serializer->serialize($object);

Deserializing Objects

You can also unserialize objects from JSON representation. For example, when accepting data via an API.

    <?php
    //get Fully\Qualified\ClassName
    $object = $this->getClassName();
    //get Serializer
    $serializer = $this->getSerializer();
    $object = $serializer->unserialize($jsonData, $object);
    //Unserialize array of the objects
    $objects = $serializer->unserialize($jsonData, array($object));
    //Unserialize specific groups
    $serializer->setGroups(array('get'));
    $object = $serializer->unserialize($jsonData, $object);
    //Unserialize specific version
    $serializer->setVersion('1.0');
    $object = $serializer->unserialize($jsonData, $object);
    //Strict unserialize mode
    $serializer->setStrictUnserializeMode(2);
    $object = $serializer->unserialize($jsonData, $object);
    //Medium Strict unserialize mode
    $serializer->setStrictUnserializeMode(1);
    $object = $serializer->unserialize($jsonData, $object);
    //Non-Strict unserialize mode
    $serializer->setStrictUnserializeMode(0);
    $object = $serializer->unserialize($jsonData, $object);
