*Danek\\Validator* is a very small validation library, with the easiest and most usable API we could possibly create.

Install
-------

[](#install)

To easily include *Danek\\Validator* into your project, install it via [composer](https://getcomposer.org) using the command line:

```
composer require danek/validator
```

Small usage example
-------------------

[](#small-usage-example)

```
use Danek\Validator\Validator;

$v = new Validator;

$v->required('user.first_name')->lengthBetween(2, 50)->alpha();
$v->required('user.last_name')->lengthBetween(2, 50)->alpha();
$v->required('newsletter')->bool();

$result = $v->validate([
    'user' => [
        'first_name' => 'John',
        'last_name' => 'D',
    ],
    'newsletter' => true,
]);

$result->isValid(); // bool(false).
$result->getMessages();
/**
 * array(1) {
 *     ["user.last_name"]=> array(1) {
 *         ["Length::TOO_SHORT"]=> string(53) "last_name is too short and must be 2 characters long."
 *     }
 * }
 */
```

Functional features
