The package provides a way to create and hydrate objects from a set of raw data.
Features are:
- supports properties of any visibility;
- uses constructor arguments to create objects;
- resolves dependencies when creating objects using PSR-11 compatible DI container provided;
- supports nested objects;
- supports mapping;
- allows fine-tuning hydration via PHP attributes.
Requirements
- PHP 8.1 - 8.5.
Installation
The package could be installed with Composer:
composer require yiisoft/hydrator
General usage
To hydrate existing object:
use Yiisoft\Hydrator\Hydrator; $hydrator = new Hydrator(); $hydrator->hydrate($object, $data);
To create a new object and fill it with the data:
use Yiisoft\Hydrator\Hydrator; $hydrator = new Hydrator(); $object = $hydrator->create(MyClass::class, $data);
To pass arguments to the constructor of a nested object, use nested array or dot-notation:
final class Engine { public function __construct( private string $name, ) {} } final class Car { public function __construct( private string $name, private Engine $engine, ) {} } // nested array $object = $hydrator->create(Car::class, [ 'name' => 'Ferrari', 'engine' => [ 'name' => 'V8', ] ]); // or dot-notation $object = $hydrator->create(Car::class, [ 'name' => 'Ferrari', 'engine.name' => 'V8', ]);
That would pass the name constructor argument of the Car object and create a new Engine object for engine
argument passing V8 as the name argument to its constructor.
