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。
