I've got a question about Spreadsheet Excel.

Hello!! This is Sun Ho working as volunteer in Nepal. Nowadays, I'm testing Pear Packages. I've got a questing for using the package of Spreadsheet Excel. I want to make the download page for storing data form DB server formed excel file. I'm wondering that I can't use php functions (for example : echo) with Spreadsheet Excel Writer. In the below, that is my test page that is same example codes on the pear site. I only appended one line. (echo "Test!!";) But, I couldn't see "Test!!" on the web page. What is my problem? How can I solve this program? I guess that the problem is from the init setting of pear. Could you help me? I really want to receive your advice. Thank You!! ----------- test page --------------- <?php echo "Test!!"; require_once("../config.php"); require_once 'Spreadsheet/Excel/Writer.php'; $workbook = new Spreadsheet_Excel_Writer(); $format_bold =& $workbook->addFormat(); $format_bold->setBold(); $format_bold->setAlign("right"); $format_title =& $workbook->addFormat(); $format_title->setBold(); $format_title->setSize(15); // let's merge //$format_title->setAlign('merge'); $worksheet =& $workbook->addWorksheet(); $worksheet->write(0, 0, "Quarterly Profits for Dotcom.Com", $format_title); // Couple of empty cells to make it look better $worksheet->write(0, 1, "", $format_title); $worksheet->write(0, 2, "", $format_title); $worksheet->write(2, 0, "Quarter", $format_bold); $worksheet->write(2, 1, "Profit", $format_bold); $worksheet->write(3, 0, "Q1"); $worksheet->write(3, 1, 0); $worksheet->write(4, 0, "Q2"); $worksheet->write(4, 1, 0); $workbook->send('test.xls'); $workbook->close(); ?> ----------- test page --------------- -- * --------------------------------------------------------------- * Sun Ho, Baek KOICA Volunteer
