README
Cereal is a PHP package that allows you to easily serialize and deserialize your data.
Installation
You can install the package via composer:
composer require youcanshop/cereal
Usage
To start using the package, you need to create a class that implements the YouCanShop\Cereal\Contracts\Serializable
interface, and use the YouCanShop\Cereal\Cereal
trait which
contains some helpers for a default configuration.
class User implements Serializable { use Cereal; public int $age; public string $name; public float $weight; public bool $isStraight; public function __construct( string $name, int $age, float $weight, bool $isStraight ) { $this->age = $age; $this->name = $name; $this->weight = $weight; $this->isStraight = $isStraight; } public function serializes(): array { return ['name', 'age', 'weight', 'isStraight']; } }
The serializes
method returns an array of the properties that you want to serialize. Then the package will automatically serialize and deserialize the data based on the type
hinted properties.
Note
- The package will only serialize public properties that are type hinted.
- The package will serialize properties in the order they are defined in the
serialize
method.
Serialization Handlers
In most uses cases, you will need to serialize and deserialize some properties in a different way. For example, you may want to serialize a DateTime
object to a timestamp, or
serialize a User
object to an array or something.
For that, you're going to create your own serialization handler and add it to the YouCanShop\Cereal\SerializationHandlerFactory
.
class UserHandler implements SerializationHandler { protected UserRepository $userRepository; public function __construct(UserRepository $userRepository) { $this->userRepository = $userRepository; } public function serialize(Serializable $serializable, $value): string { return $value->getId(); } /** * @param string $value * * @return ?User */ public function deserialize(Serializable $serializable, $value): ?User { return $this->userRepository->find($value); } }
In the above example, when trying to serialize a user object, we serialize only the ID, and when trying to deserialize it, we fetch it again from database.
Then, you need to add your handler to the YouCan\Cereal\SerializationHandlerFactory
:
use YouCan\Cereal\SerializationHandlerFactory; SerializationHandlerFactory::getInstance() ->addHandler(User::class, new UserHandler($userRepository));
Now, when working with our object that will be serialized, and if it contains a User
instance, it will automatically be serialized and deserialized using our handler.
class Post implements Serializable { use SerializeTrait; public string $title; public string $content; public User $author; public function __construct(string $title, string $content, User $author) { $this->title = $title; $this->content = $content; $this->author = $author; } public function serializes(): array { return ['title', 'content', 'author']; } }
