这已经是一个副本，我如何在PHP中输出一个UTF-8 CSV, Excel将正确读取?

但是你需要包含一个字节顺序标记。可以这样做:https://stackoverflow.com/a/7601168/678611

<?php
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename=<a filename>.csv');
header('Content-Transfer-Encoding: binary');
echo "xEFxBBxBF"; // Byte Order Mark
echo $the_csv_file_content;
exit();
?>
