For people who want their data exported in an excel format checkout this chunk of code. It’s really easy :-) First of all you need to download this php excel class Now try this code: $query = mysql_query("select * from table"); while($q = mysql_fetch_assoc($query)){ $output[] = $q; } require_once "excel.php"; $export_file = "xlsfile://export.xls"; $fp = fopen($export_file, "wb"); if (!is_resource($fp)) { die("Cannot open $export_file"); } fwrite($fp, serialize($output)); fclose($fp); header ("Content-Type: application/x-msexcel"); header ("Content-Disposition: attachment; filename=\"exports.xls\"" ); readfile("xlsfile://export.xls"); exit; That’s got to be the easiest thing you have ever done in PHP.
