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.
