If you are referring to an Excel header, append the form to the content in front of the body.
if (Is_array ($title)) {
Array_unshift ($data, $title);

The above is my code, I use thinkphp framework, the second picture is the effect of the export, where the problem arises, how to solve?
------Solution--------------------
Now that you're using thinkphp, it's supposed to be utf-8.
The default character set for Phpexcel is also utf-8
Then why should
$VV = Iconv ("UTF-8", "Gb2312//ignore", $VV);
Turn the utf-8 into gb2312?


------Solution--------------------
Can't you read it? Did I not make myself clear? Looks like you can't accept the heuristic.

Delete all statements that use Iconv transcoding!
That should be clear, right?
Phpexcel written to Excel must be UTF-8 encoded data
That should be understood, right?

------Solution--------------------
Turn to GBK look, another iconv to Mars and traditional characters will have problems
$VV = mb_convert_encoding ($VV =, "GBK", "UTF-8");
------Solution--------------------
38 no need to delete

If you can't, just put a
------Solution--------------------
Yes, it's turned back.

As I said earlier, it's no problem for me to test your code snippets alone.
So the problem might be somewhere else: incoming data, data read from a table, even the Phpexcel class you're using.

Include ' plugin/phpexcel/classes/phpexcel.php ';
        import (' Org.Util.PHPExcel.IOFactory ');
        import (' PHPExcel.Util.PHPExcel.Reader.Excel5 ');
