Input hydrator is a simple hydrator made for the sole purpose of hydrating data-transfer input objects.

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

[](#installation)

```
$ composer require azjezz/input-hydrator
```

Example:
--------

[](#example)

```
use AzJezz\Input;

final class Search implements Input\InputInterface
{
    public string $query;
}

/**
 * @var Search $search
 */
$search = (new Input\Hydrator())->hydrate(Search::class, $_GET);

print $search->query;
```

While hydrating objects, some exceptions might be thrown:

- `AzJezz\Input\Exception\TypeException`: this exception should result in 500 HTTP status code, as it represents an issue within the input class itself. such as the usage of a non-supported type, or missing type for a specific property.
- `AzJezz\Input\Exception\BadInputException`: this exception should result in a 400 HTTP status code, as it means that the supplied request data doesn't match the input DTO structure.

Currently, Input-Hydrator is limited to a small set of types:

- `scalar` ( `string`, `int`, `float`, and `bool` )
- `null`
- *any object that implements `AzJezz\Input\InputInterface`*

Union types are supported for PHP >= 8.0, for example:

```
use AzJezz\Input;

final class Filter implements Input\InputInterface
{
    public ?int $maximumPrice;
    public ?int $minimumPrice;
}

final class Search implements Input\InputInterface
{
    public string $query;
    public null|Filter|string $filter = null;
}

/**
 * $filter is optional, and is missing from the request, therefore it's gonna contain the default value.
 *
 * @var Search $search
 */
$search = (new Input\Hydrator())->hydrate(Search::class, [
  'query' => 'hello'
]);

/**
 * $search->filter is now an instance of `Filter`
 *
 * @var Search $search
 */
$search = (new Input\Hydrator())->hydrate(Search::class, [
  'query' => 'hello',
  'filter' => [
    'maximum_price' => 1000,
    'minimum_price' => 10, // the field is optional ( nullable ), so we can remove this line.
  ]
]);

/**
 * $search->filter is now a string
 *
 * @var Search $search
 */
$search = (new Input\Hydrator())->hydrate(Search::class, [
  'query' => 'hello',
   // this is okay as the `null|Filter|string` union contains `string`
  'filter' => 'maximum_price=1000&minimum_price=10',
]);

print $search->query;
```
