# ArrayVal

- `ArrayVal()`

Validates if the input is an array or if the input can be used as an array
(instance of `ArrayAccess` or `SimpleXMLElement`).

```php
v::arrayVal()->validate([]); // true
v::arrayVal()->validate(new ArrayObject); // true
v::arrayVal()->validate(new SimpleXMLElement('<xml></xml>')); // true
```
