Hydrator

This library gives you the possibility to hydrate your anemic models even if they contains private properties.

Installation

composer require anonymous-php/hydrator

Example

<?php

require __DIR__ . '/vendor/autoload.php';

use Anonymous\Hydrator\Hydrator;

class Vehicle
{
    private $doors;
    private $seats;
}

$hydrator = new Hydrator();

$model = new Vehicle();
$data = ['doors' => 3, 'seats' => 2];

$hydrator->hydrate($data, $model);

var_dump($model);

$properties = $hydrator->extract($model);

var_dump($properties);

/*
    object(Vehicle)#3 (2) {
      ["doors":"Vehicle":private]=>
      int(3)
      ["seats":"Vehicle":private]=>
      int(2)
    }
    array(2) {
      ["doors"]=>
      int(3)
      ["seats"]=>
      int(2)
    }
*/

Extending

<?php

require __DIR__ . '/vendor/autoload.php';

use Anonymous\Hydrator\DynamicHydrator;

class CustomHydrator extends DynamicHydrator
{

    protected function getGetterName(string $property): string
    {
        return 'get' . $this->prepareName($property) . 'Attribute';
    }

    protected function getSetterName(string $property): string
    {
        return 'set' . $this->prepareName($property) . 'Attribute';
    }

}

Benchmark

    public function getFoo() { return $this->foo; }
    public function getBar() { return $this->bar; }
