NYCPHP Meetup

[haha]

Thanks,  Phil, 
your code is a great help, but it doesn't work for me. I finally
got this, and it works. Thank you for your great help!!

   header("Content-Type: application/vnd.ms-excel;
charset=$dest_charset");
   header("Cache-Control: must-revalidate, post-check=0,
pre-check=0");
   print($report_content);

This code works for both IE and Netscape.

It looks lilke a cach issue.

It's because Internet Explorer honors the no-cache and no-store pragmas.
This equates to it not wanting to save anything to disk.

When downloading files - in a RFC standard world - you should add some
headers to allow caching/downloading.  Such as

      header('Cache-Control: must-revalidate', TRUE);
      header('Pragma: ', TRUE);
