    }

}

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。
