demo:

require_once('./Validator.class.php');$data = array(        'nickname' => 'heno' ,        'realname' => 'steven',        'age' => 25,        'mobile' => '1521060426');$validator = new Validator($data);$validator->setRule('nickname', 'required');$validator->setRule('realname', array('length' => array(1,6), 'required'));$validator->setRule('age', array('required', 'digit'));$validator->setRule('mobile', array('mobile'));$result = $validator->validate();var_dump($result);var_dump($validator->getResultInfo());
