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 == 'utf-8')
{
echo ecs_iconv(EC_CHARSET, 'GB2312', $data);
}
else
{
echo $data;
}
?>Note: The character conversion step can be omitted according to actual needs.
