# 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()->assert([]);
// Validation passes successfully

v::arrayVal()->assert(new ArrayObject);
// Validation passes successfully

v::arrayVal()->assert(new SimpleXMLElement('<xml></xml>'));
// Validation passes successfully
```
