PHP 处理JOSN数据 Json转

$dataJson = json_decode($collection_list);
    $code = $dataJson->code;
    if ($code == 1) {
        $dataArrayList = $dataJson->data;
        $collectionStr = "";
        foreach ($dataArrayList as $value) {
            $gid = $value->gid;
            $collectionStr .= "or `id` = '{$gid}' ";
        }

        $collectionStr = ltrim($collectionStr, "or ");
        $qstr .= $collectionStr;
    } else if ($code == 0) {
        exitByAPPOKDate("查询成功");
    } else {
        exitByAPPFailedDate("失败了");
    }

{“code” : 1  }

字符串转换成json后可以直接使用->code取出数据也就是1

那么如果data是一个数组 可以参照上面的方式进行快速序列化。
