Callback
v::callback(callable $callback)
This is a wildcard validator, it uses a function name, method or closure to validate something:
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.
