Write your validation rule like this:

public function rules() {
  return [
    ['input', 'required'],
    ['input', function($attribute, $params) {
      if (is_integer($this->$attribute)) {
 				//если число
 				if ($this->attribute < 10) {
 					return $this->addError($attribute, 'Число должно быть больше 10');
 				}
      }

      if (is_string($this->$attribute)) {
        //ecли строка
      }			
  }],
];
}
