# 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()->isValid([]); // true
|
|
v::arrayVal()->isValid(new ArrayObject); // true
|
|
v::arrayVal()->isValid(new SimpleXMLElement('<xml></xml>')); // true
|
|
```
