The most awesome validation engine ever created for PHP.
 .
  * Complex rules made simple:
    v::numeric()->positive()->between(1, 255)->validate($input)
  * Granularity control for advanced reporting.
  * More than 100 (fully tested) validators.
  * A concrete API for non fluent usage.
  * Works on PHP 5.4+ or HHVM 3.3+
