# 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.
