php 二进制unpack、汉字转码

header("Content-Type: text/html;charset=utf-8");
$data=$redis->hGetAll("$label");   //从redis读数据;$data包括两个元素：name为GB2312汉字，k1为二进制数据

//解压二进制数据
$doc= (string)$data['k1'];
$format = 'itime/flast/fop/fhi‘;
$arr0 = unpack($format,$doc);//合并解压后数据$arr0与$l两个数组
$l["label"]=$label;$l["name"]=iconv('GB2312','UTF-8//IGNORE',(string)$data['name']);//转换GB2312汉字为UTF-8
$arr=array_merge($l,$arr0);//追加至$res数据，返回数据
array_push($res['data'],$arr);
echo json_encode($res);
        循环执行上述代码时总不能输出正确数据。单独输出解压后的二进制数据没问题，单独转换GB2312汉字为UTF-8输出也没问题。但两者放一起，要么输出name为null、要么数据变乱，同时语句顺序对结果也有影响。
请高手指点。

需要看到原始数据，才能判断是否是算法问题
echo base64_code(serialize($daya));
贴出结果
array(2) { ["k1"]=> string(48) "d>�Y�G�@ף�@33�@ף�@\��@�k>K�B�B��F" ["name"]=> string(8) "��۾�" }
array(2) { ["k1"]=> string(48) "d>�Y�eA��dA��dA)\cA�cA A��K�B�C��F" ["name"]=> string(8) "�㶫��" }
这是var_dump($data);的数据。
echo base64_code(serialize($data['k1']));无显示数据。
            $l["label"]=$label;$l["name"]=iconv('GB2312','UTF-8//IGNORE',$doc['name']);
            print_r($l);
            echo $l["name"];
这几句话，结果name为空。
           name能出来了。但unpack处有问题，页面显示502错误            $l["label"]=$label;$l["name"]=iconv('GB2312','UTF-8//IGNORE',$data['name']);
            //print_r($l);echo $l["name"];
            $format = 'it/fl/fo/fh/flo/fcl/fv/fam/fop/fb/fs/ftotlVo';
            $arr0 = unpack($format,$data['k1']);//不能执行
echo base64_encode(serialize($data));
echo base64_encode(serialize($data))结果：

谢谢。但没解决问题，问题依然存在:
     iconv('GB2312','UTF-8//IGNORE',$data['name']);  这句改变了$data的值
源代码：
            var_dump($data);
            echo iconv('GB2312','UTF-8//IGNORE',$data['name']).'<br />';
            var_dump($data);结果：
    array(2) { ["k1"]=> string(48) "��Y{��B=��BH�B ׸B= �B" ["name"]=> string(8) "��Ԫָ��" }
    美元指数
    array(2) { ["k1"]=> string(12) "美元指数" ["name"]=> string(8) "��Ԫָ��" }
你的程序可以正常执行。我改了下不行，请再帮忙看下
            $doc=array();
            $data=$redis->hGetAll("$label");
            $doc=(array)$data;
            $format = 'itime/flastClose/fopen/fhigh/flow/fclose/fvol/famount/fopid/fbv/fsv/ftotalVol';
            $doc['label']=$label;
            $doc['name'] = mb_convert_encoding($doc['name'], 'UTF8', 'GBK');
            $doc['k1'] = unpack($format, $doc['k1']);
            print_r ($doc);结果：
       Array ( [open] => 只有这个，这是哪方面的问题？
上述代码在如下循环中：
        foreach ($listData as $label)
        {
            $doc=array();
            $data=$redis->hGetAll("$label");
            $doc=(array)$data;
            $format = 'itime/flastClose/fopen/fhigh/flow/fclose/fvol/famount/fopid/fbv/fsv/ftotalVol';
            $doc['label']=$label;
            $doc['name'] = mb_convert_encoding($doc['name'], 'UTF8', 'GBK');
            $doc['k1'] = unpack($format, $doc['k1']);
            print_r ($doc);
        }
