导出mysql数据到excel时的错误信息

“database.xls”的文件格式和扩展名不匹配。 该文件可能已损坏或不安全。 除非你信任它的来源，否则不要打开它。 你想打开吗？
我已经尝试过不同的文件扩展名，但无法修复它。
错误的原因是您正在创build一个文本文件，其中字段由选项卡分隔，而不是Excel文件。
只需更改线路：
header("Content-Type: application/xls"); header("Content-Disposition: attachment; filename=$filename.xls");
有：
header("Content-Type: text/plain"); header("Content-Disposition: attachment; filename=$filename.txt");
或者，或者：
header("Content-Type: text/csv"); header("Content-Disposition: attachment; filename=$filename.csv");
然后你可以从Excel打开这个文件。
