# In
- `v::in(mixed $haystack)`
- `v::in(mixed $haystack, boolean $identical = false)`
Validates if the input is contained in a specific haystack.
For strings:
```php
v::in('lorem ipsum')->validate('ipsum'); // true
```
For arrays:
```php
v::in(['lorem', 'ipsum'])->validate('lorem'); // true
```
A second parameter may be passed for identical comparison instead
of equal comparison.
Message template for this validator includes `{{haystack}}`.
