Serializer

Based on GeneratedHydrator, it serializes recursively, adding metadata to the generated array in order to be able to deserialize an object without knowing its type beforehand.

Installation

Serializer can be found on Packagist. The recommended way to install Serializer is through composer.

Run the following on the command line:

composer require remi-san/serializer=@stable

And install dependencies:

composer install

Usage

$classMapper = new RemiSan\Serializer\Mapper\DefaultMapper(
    new RemiSan\Serializer\NameExtractor\DefaultNameExtractor()
);
$classMapper->register(RemiSan\Serializer\Sample\MySampleClass::class);

$serializer = new RemiSan\Serializer\Serializer(
    $classMapper,
    new RemiSan\Serializer\Hydrator\HydratorFactory(__DIR__ . '/proxies', true),
    new RemiSan\Serializer\Formatter\FlatFormatter(),
    new Doctrine\Instantiator\Instantiator()
);

$object = new MySampleClass(new MySampleClass());
$serialized = $serializer->serialize($object);
$deserialized = $serializer->deserialize($serialized);

Command usage

When installing through composer, a CLI command is also made available (in vendor/bin/ or bin/ according to your composer.json):

bin/serializer generate:cache <cache-path> <fully-qualified-class-name>

It will write the cached version of the hydrator for the requested class in the path you provided.

You'll have to generate cached files for all your serializable classes when running in production (with the generateProxies option of the HydratorFactory set to `false).

You'll also have to make the autoloader aware of your hydrators by adding the following to your composer.json:

{
    "autoload": {
        "classmap": [
            "/path/to/cache-dir"
        ]
    }
}

Details

To be instantiated, the Serializer needs a SerializableClassMapper, a HydratorFactory, a DataFormatter and an Instantiator.

SerializableClassMapper is used to register the classes the serializer will be able to (de-)serialize. It needs a SerializableClassNameExtractor which will be able to normalize the name of the class the way you want it.

HydratorFactory will retrieve the hydrators needed to deserialize data. It needs the path to the cache directory and whether or not, it should generate the proxies on runtime.

DataFormatter will provide the way the serialized array will be formatted (provided implementations allow it to format it as a 2-level array or a flat one with a _metadata key).

Instantiator will allow to instantiate an object without the constructor based on the fully qualified class name of the requested object.
