        $map['goods_id'] = array('in',$this->returnid()); 
        $result = $this->showgoods($map); 
        //写入CSV并保存数据     
        $header =iconv('UTF-8','GB2312',"宝贝名称,宝贝类目,店铺类目,新旧程度,省,城市,出售方式,宝贝价格,加价幅度,宝贝数量,有效期,运费承担,平邮,EMS,快递,付款方式,支付宝,发票,保修,自动重发,放入仓库,橱窗推荐,开始时间,心情故事,宝贝描述,宝贝图片,宝贝属性,团购价,最小团购件数,邮费模版ID,会员打折,修改时间,上传状态,图片状态,返点比例,新图片,视频,销售属性组合,用户输入ID串,用户输入名-值对,商家编码,销售属性别名,代充类型,宝贝编号");

        header('Cache-Control:must-revalidate,post-check=0,pre-check=0'); 
        header('Expires:0'); 
        header('Pragma:public'); 
        echo "$header\n"; 

        //输出数据体 
        foreach($result as $value) 
        { 
//过滤描述字段 
            $desc = csvdatafilter("www.yibaikuan.com",$value['goods_desc']); 
//截取图片文件名 
            $img = msubstr($value['goods_thumb'],24,25); 
            //转义 

            $body =iconv('UTF-8','GB2312',$value['goods_name'].",,,0,浙江,金华,b,".$value['shop_price'].",0,".$value['goods_number'].",14,1,20,20,10,,,0,0,1,0,1,,,".$desc.",,,,,0,0,,100,,0,".$img.":0:0:|;,,,,,,,0,");
