把資料存入EXCEL，並不下載

把資料匯至excel，並存放在server上
參考：pear
require_once("PEAR/Writer.php");
//Excel檔名
$filename = "ExcelText.xls";
$sheet_1 = "SHEET";
$analys =new Analyse;
$workbook = new Spreadsheet_Excel_Writer($filename); //新增Excel
$worksheet =& $workbook->addWorksheet($sheet_1); //新增sheet
$worksheet->write(0,0,"Error"); //寫資料至Excel
$workbook->close();
因為下載，所以不用寫 send
