Fastest hydrator

Hydrator.php

<?php
class Test {
    private $a='data';

    protected $b=123;

    public $c=true;
}


class Hydrator
{
    private function getContext()
    {
        return get_object_vars($this);
    }

    public function __invoke($object)
    {
        static $hydrator = null;
        if (!$hydrator) {
            $hydrator = (new ReflectionMethod(__CLASS__, 'getContext'))->getClosure($this);
        }
        return $hydrator->bindTo($object, get_class($object))->__invoke($object);
    }
}

$a = new Test;
$hydrator = new Hydrator();
$data = $hydrator($a);
var_dump($data);

// OUTPUT:
array (size=3)
  'a' => string 'data' (length=4)
  'b' => int 123
  'c' => boolean true

Not the fastest hydrator =D (also misses writes, which is my current problem :( )

Try running https://github.com/Ocramius/ProxyManager/blob/master/examples/hydrator.php and look at the generated code :)

The problems are with parent classes and private properties, and writes to private properties in general (currently done via reflection).
