        $str = "序号,配件名称,供应商,入库时间,采购员,进价\n";
        foreach($orderModel as $key=>$value) {
            $keys = $key+1;
            $accessorie_name = $value['accessorie_name'];

            $str .= $keys.",".$accessorie_name.",".$supplier_name.",".date('Y-m-d H:i:s',$create_time).",".$buyer_name.",".$buy_price."\n"; //用引文逗号分开
        }
    
        $filename = 'RuKuChaXun'.date('Ymdhis').'.csv'; //设置文件名

        $str= iconv('UTF-8', 'GBK//IGNORE', $str);  //不加会出现乱码
        echo $str;
