# Callback
- `v::callback(callable $callback)`
This is a wildcard validator, it uses a function name, method or closure
to validate something:
```php
v::callback('is_int')->validate(10); // true
```
(Please note that this is a sample, the `v::intVal()` validator is much better).
As in `v::call()`, you can pass a method or closure to it.
