PHP Pack Export Data Inverted Excel table Chinese garbled problem

Need to use PHP to export data into the Excel table, using the PHP Pack function to package the characters into binary, and then write to Excel table file, English characters import normal, now Chinese characters are all garbled, do not know where to set the problem?

  title = $title;    $this->col = 0;    $this->row = 0;    $this->data = ";  $this->bofmarker (); }/** * Transmits the proper headers to cause a download to occur and to identify the file properly * @return Nothi    NG */Function headers () {header ("content-type:application/force-download");    Header ("Content-type:application/octet-stream");    Header ("Content-type:application/download"); Header ("Content-type:application/vnd.ms-excel;    Charset=iso-8859-1 "); Header ("Content-disposition:attachment;filename=".

Here is my call to test the code:

  
    $value) {        $xls->home();        foreach ($value as  $row) {          // $xls->home();          $xls->label($row);          $xls->right();           // $xls->label($row);        }        $xls->down();    }        ob_start();    $xls->send();    $data = ob_get_clean();    file_put_contents(__DIR__ .'/report.xls', $data);

What is the code of your Chinese? Excel is GB2312 by default. If the UTF-8 is garbled.

Solution: Either turn it into a GB2312 and write it in.
Or output BOM header at the end of the first

    ob_start();    $xls->send();    $data = "\xEF\xBB\xBF" . ob_get_clean();    file_put_contents(__DIR__ .'/report.xls', $data);
