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](https://www.php-fig.org/psr/psr-11/) compatible DI container provided;
- supports nested objects;
- supports mapping;
- allows fine-tuning hydration via PHP attributes.

Requirements
------------

[](#requirements)

- PHP 8.1 - 8.5.

Installation
------------

[](#installation)

The package could be installed with [Composer](https://getcomposer.org):

```
composer require yiisoft/hydrator
```

General usage
-------------

[](#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.
