验证器类：$validate=new \think\Validate($rule,$message,$field);
独立验证：
//独立验证$rule=[ ???‘name‘ ?=> ‘require|max:25‘, ???‘email‘ => ‘email‘]$msg=[ ???‘name.require‘ => ‘名称必须‘, ???‘name.max‘ ????=> ‘名称最多不能超过25个字符‘, ???‘email‘ ???????=> ‘邮箱格式错误‘, ???];$field = [ ???‘name‘ ?=> ‘名称‘, ???‘email‘ => ‘邮箱‘, ???];$validate = new Validate($rule,$msg,$field); $data = [ ???‘name‘ => ‘thinkphp‘, ???‘email‘ => ‘thinkphp@qq.com‘]; if (!$validate->check($data)) { ???dump($validate->getError());}make、rule、extend、setTypeMsg、message、scene、hasscene、batcch、check、getError
验证器：定义在模块下的validate文件夹内;
注意：Call to undefined function mb_strlen() ：开启：extension=php_mbstring.dll； 还不行就就看看这extension_dir = "ext";还不行就绝对路径
