**Validator** is [Schematicon Schema](https://github.com/schematicon/spec) validator. Schemeaticon schema is innovative declarative language for data structure description. It is programming-language independent; that means you can define the schema using [NEON](https://ne-on.org/), YAML or native PHP arrays.

### Example

[](#example)

`my_family.neon`:

```
type: map
properties:
    name: string
    surname: string
    sex:
        enum: [male, female]
    age: int|null # property may be a null
    ?height: float # property may not exist at all; if exist, it has to be a float
    siblings:
        type: array
        item:
            type: string
```

The following inputs may be validated againts the defined schema:

```
$normalizer = new Schematicon\Validator\Normalizer();
$schema = Neon\Neon::decode(file_get_contents('./my_family.neon'));
$schema = $normalizer->normalize($schema);
$validator = new Schematicon\Validator\Validator($schema);

$result = $validator->validate([
	'name' => 'jon',
	'surname' => 'snow',
	'sex' => 'male',
	'age' => 18,
	'height' => 180.00,
	'siblings' => ['Arya'],
]);

$result->isValid(); // true
$result->getErrors(); // []
```
