# IterableVal
|
|
|
|
- `IterableVal()`
|
|
|
|
Validates whether the input is an iterable value, in other words, if you can iterate over it with the [foreach][] language construct.
|
|
|
|
```php
|
|
v::iterableVal()->isValid([]); // true
|
|
v::iterableVal()->isValid(new ArrayObject()); // true
|
|
v::iterableVal()->isValid(new stdClass()); // true
|
|
v::iterableVal()->isValid('string'); // false
|
|
```
|
|
|
|
## Note
|
|
|
|
This validator doesn't behave as PHP's [is_iterable() function because it considers that you can iterate over any object.
