An experiment with combining PHPdoc comments and type-hinting.

At the moment, it allows for strict type checking for public properties and methods. It could provide type casting for scalar values.

You probably shouldn't use this, it'll be slow.

Wrapping an object through CastWrapper proxies attribute-setters and method calling through checks that inspect the doc-comment of the method or property.

use Rmasters\ReflectionCast\CastWrapper;

class User {
    private $id;

    /** @var bool */
    public $enabled;

    /**
     * @param int $id
     */
    public function setId($id) {
        $this->id = $id;
    }
}

$user = new CastWrapper(new User);
$user->setId(123);  // okay
$user->setId("42"); // throws InvalidArgumentException

$user->enabled = false; // okay
$user->enabled = "okay"; // throws InvalidArgumentException

• Make a better interface (traits?)
• Test non-scalar hints, arrays (e.g. stdClass[])
• Support constructors
• Cache doc-comments rather than parsing each time
