基本满足需求。
vendor('Func.Valid'); if ($res = Valid::validate('152','required|regex,/^1[345678]{1}\d{9}$/')) { $this->json->setErr(10001,$res); $this->json->Send(); }
封装很有意思，这个类唯一的亮点，就是可以复合验证。并且支持正则。而且里面的验证方法还可以单独使用。
vendor('Func.Valid'); if (!Valid::check_tel('152')) { $this->json->setErr(10001,'手机号有误'); $this->json->Send(); }
勇敢的封装，利国利民。
继续封装，支持数组传参。
