是不是ci的bug

无所谓了嘛

建立一个demo案例,执行如下代码：
        $para_filter  = array();
        $para = $_GET;
        print_r($_GET);
        while (list ($key, $val) = each ($_GET)) {
                if($key == "sign" || $key == "sign_type" || $val == "")continue;
                else        $para_filter[$key] = $para[$key];
        }
        print_r($para_filter);
        exit();

GET参数如下：
?buyer_email=wusuoweilema%40163.com&buyer_id=2088002167967008&exterface=create_direct_pay_by_user&is_success=T¬ify_id=RqPnCoPm3K9%252Fvwbh3InUEWHvA6UslzTAGrwpxB%252BFwtWtiuHZbck293fWBfssY3pWumfd¬ify_time=2016-03-05+18%3A39%3A06¬ify_type=trade_status_sync&out_trade_no=1106438735022023&payment_type=1&seller_email=279592358%40qq.com&seller_id=2088111192705735&subject=%E5%88%B0%E6%AD%A4%E4%B8%80%E6%B8%B8%E5%95%86%E5%93%81%E8%B4%AD%E4%B9%B0%E8%AE%A2%E5%8D%95%E6%94%AF%E4%BB%98%3A1606438735022023&total_fee=0.01&trade_no=2015030521001004220263134740&trade_status=TRADE_SUCCESS&sign=1029b82e1db9da7e8527b376f3b4e99d&sign_type=MD5

代码结果为：

buyer_email参数不见了
上面的代码如果是在php纯环境下：没有问题，在ci3.02和3.04下都有问题。

没看明白跟 CI 有什么关系？$_GET 我看没有丢失 buyer_email 参数呀？

这个不关CI的事   还别忘了CI就是PHP的框架   我也用CI3.0.3使用支付宝完全没有问题的
