# Iterable
|
|
|
|
- `v::iterable()`
|
|
|
|
Validates if the input is iterable, in other words, if you're able to iterate
|
|
over it with [foreach](http://php.net/foreach) language construct.
|
|
|
|
```php
|
|
v::iterable()->validate([]); // true
|
|
v::iterable()->validate(new ArrayObject()); // true
|
|
v::iterable()->validate(new stdClass()); // true
|
|
v::iterable()->validate('string'); // false
|
|
```
