PHP sets HTTP header information to export Excel report

No need to use fputcsv function to generate reports. Just set the corresponding format and HTTP header information to generate the report. Attached code:

<?php
header("Content-type: application/vnd.ms-excel; charset=utf-8");
header("Content-Disposition: attachment; filename=excel.xls");
$data  = "分类销售统计\t\n";
$data .= "排名\t产品大类\t销售额（万）\t销售占比\t单品数量\n";
if (EC_CHARSET == &#39;utf-8&#39;)
{
      echo ecs_iconv(EC_CHARSET, &#39;GB2312&#39;, $data);
}
else
{
      echo $data;
}
?>

Note: The character conversion step can be omitted according to actual needs.
