Lo script funziona perfettamente, ma è possibile salvare automaticamente su server un file excel generato con il seguente codice ?.....

<?
$filename="sheet.xls";
header ("Content-Type: application/vnd.ms-excel");
header ("Content-Disposition: inline; filename=$filename");
?>

// codice html e php


...... ?
