# 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
|
|
```
