Why?
Component to serialize & deserialize object, mainly use by client SDK to (de)serialize VO for cache
Installation
If you wish to install it in your project, require it via composer:
composer require eureka/component-serializer
Usage
Simple (un)serialization
This library will provide a (un)serializer service to allow safe caching of value objects.
<?php namespace Application; use Application\VO\AnyObject; use Eureka\Component\Serializer\JsonSerializer; $serializer = new JsonSerializer(); $originalVO = new AnyObject(1, 'name', 'any arg'); //~ Serialize a VO into json string $json = $serializer->serialize($originalVO); //~ Unserialize a serialized VO $unserializedVO = $serializer->unserialize($json, Application\VO\AnyObject::class);
To allow correct serialization & unserialization, the VO must implement \JsonSerializable
interface and use
the provided JsonSerializableTrait
. This trait handle automatically the sub VO for the (un)serialization.
For a list off sub VO (collection), a collection object must be provided in constructor.
Complex (un)serialization with collection
First, you need to have a collection object. We provide an AbstractCollection class to manage all base operation.
So, create a Collection class:
<?php declare(strict_types=1); namespace Application\VO; use Eureka\Component\Serializer\Exception\CollectionException; use Eureka\Component\Serializer\VO\AbstractCollection; class CollectionEntityB extends AbstractCollection implements \JsonSerializable { /** * Class constructor. * * @param array */ public function __construct(array $dataEntitiesB) { foreach ($dataEntitiesB as $dataEntityB) { $this->add(new EntityB($dataEntityB['id'], $dataEntityB['name'])); } } /** * Override parent method to ensure we have only required sub VO entity. * * @param mixed $offset * @param mixed $value * @return void * @throws CollectionException */ public function offsetSet($offset, $value) { if (!$value instanceof EntityB) { throw new CollectionException('Data must be an instance of ' . EntityB::class); } parent::offsetSet($offset, $value); } }
<?php declare(strict_types=1); namespace Application\VO; use Eureka\Component\Serializer\JsonSerializableTrait; class EntityA implements \JsonSerializable { use JsonSerializableTrait; private int $id; private string $name; private ?CollectionEntityB $listEntitiesB; /** * EntityA constructor. * * @param int $id * @param string $name * @param CollectionEntityB|null $listEntitiesB */ public function __construct( int $id, string $name, ?CollectionEntityB $listEntitiesB = null ) { $this->id = $id; $this->name = $name; $this->listEntitiesB = $listEntitiesB; } //... }
<?php declare(strict_types=1); namespace Application\VO; use Eureka\Component\Serializer\JsonSerializableTrait; class EntityB implements \JsonSerializable { use JsonSerializableTrait; private int $id; private string $name; public function __construct( int $id, string $name ) { $this->id = $id; $this->name = $name; } //... }
Now, try to (un)serialize VO
<?php namespace Application; use Application\VO\CollectionEntityB; use Application\VO\EntityA; use Application\VO\EntityB; use Eureka\Component\Serializer\JsonSerializer; $serializer = new JsonSerializer(); $dataList = [ ['id' => 1, 'name B#1'], ['id' => 2, 'name B#2'], ]; $originalVO = new EntityA(1, 'name', new CollectionEntityB($dataList)); //~ Serialize a VO into json string $json = $serializer->serialize($originalVO); //~ Unserialize a serialized VO $unserializedVO = $serializer->unserialize($json, Application\VO\EntityA::class); //~ Manipulate collection from unserialized entity foreach ($unserializedVO->getCollectionEntityB() as $entityB) { echo $entityB->getName() . PHP_EOL; }

file is not committed.
Testing & CI (Continuous Integration)
Tests
You can run tests (with coverage) on your side with following command:
make tests

make integration
For prettier output (but without coverage), you can use the following command:
make testdox # run tests without coverage reports but with prettified output
Code Style
You also can run code style check with following commands:
make phpcs
You also can run code style fixes with following commands:
make phpcsf
Static Analysis
To perform a static analyze of your code (with phpstan, lvl 9 at default), you can use the following command:
make analyze
Minimal supported version:
make php-min-compatibility
Maximal supported version:
make php-max-compatibility
CI Simulation
And the last "helper" commands, you can run before commit and push, is:
