Laravel 4 laravel 4.2基于管道的验证错误

提交表单时出错

错误异常E_未知

数组到字符串的转换

下面是生成不验证表单错误的代码

      $rulesvalida=array(
        'txt_name' => 'required|min:3',
        'txt_phone_number' => 'required|numeric|min:8',
        'txt_street_name' => 'required|min:3',
        'txt_house_number' => 'required|min:3',
        'txt_floor' => 'required|min:3',
        'txt_side' => 'required|min:3',
        'txt_post_code' => 'required|min:4',
        'txt_post_town' => 'required|min:4',
        'txt_country' => 'required',
    );

          return Validator::make($data, $rulesvalida, Lang::get('validation'));

错误发生在哪一行？可能是$data的错误？数组大小=8'txt\U name'=>字符串'dd'长度=2'txt\U电话号码'=>字符串'34324'长度=5'txt\U街道\U name'=>字符串'343'长度=3'txt\U房屋\U编号'=>字符串'343'长度=3'txt\U楼层'=>字符串'43'长度=2'txt\U侧'=>字符串长度=0'txt\U邮政编码'=>字符串长度=0'txt\U邮政城市'=>string length=0如果删除第三个变量Lang，情况会怎样？它还会发生吗？是的，那么它也会发生
