Generating an Excel file on the fly in a Web site

Are there any good PHP libraries for exporting data to Excel files (not CSV files)?

(An alternative would be creating an ASP.NET Web service that handles Excel file generation, but I would rather not send complex objects开发者_Python百科 over a network in XML format, unless it were strictly necessary.)

For PHP try PHPEXCEL

Excel will accept a standard HTML table masquerading as a .xls file:

<table><tr><td></td></tr></table>

Just set the file extension and mime type on download to the client.

While not a "direct export" library, the PHPExcel library looks to be a nice library for generating Excel files using PHP.

If you do go the .Net route, I highly recommend the NPOI library.
