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。

使用如下

vendor('Func.Valid');$validators = [    'tel' => 'required|tel',    'name' => 'required',    'email' => 'r|email',    'password' => 'r|min_len,6|max_len,12'];if ($err = Valid::is_valid($validators,$_POST)) {    $this->json->setErr(10001,$err);    $this->json->Send();}

继续优化！支持错误提示中，添加参数。
