        //$csv_line_data = mb_convert_encoding ($csv_line_data,"gbk","utf-8");

//windwos编码转换

                        //由于gb2312支持的字比较少，导致有些无法识别的字直接去掉了，换成支持更多字的gbk

                        //$data = iconv("utf-8","gb2312//IGNORE",$data);

                        $header_str = iconv("utf-8","gbk//IGNORE",$title1);

$csv_line_data = iconv("utf-8","gbk//IGNORE",$csv_line_data);
        //$header_str = iconv("utf-8", 'gbk', $title);
        //$csv_line_data = iconv("utf-8", 'gbk//IGNORE', $csv_line_data);

        ob_end_clean();

                //写出
