Problem with PHPexcel

Problem with PHPExcel

I stated this several time when you originally raised thsi question... that script will generate a blank page.

$objWriter->save('CityList.xls');

writes the Excel workbook to a file called CityList.xls on the server's filesystem. It does NOT display anything to the screen... therefore the screen will be blank.

Look on the server. Find the file called CityList.xls. Open that file in MS Excel.

EDIT

Alternatively, set the appropriate headers, and save to php://output

// connection with the database
$dbhost = "localhost";
$dbuser = "root";
$dbpass = "";
$dbname = "database";

mysql_connect($dbhost,$dbuser,$dbpass);
mysql_select_db($dbname);

// require the PHPExcel file
require 'Classes/PHPExcel.php';

// simple query

$query = "SELECT id FROM users ORDER by id DESC";

if ($result = mysql_query($query) or die(mysql_error())) {
    // Create a new PHPExcel object
   $objPHPExcel = new PHPExcel();
   $objPHPExcel->getActiveSheet()->setTitle('List of Cities');

   // Loop through the result set
    $rowNumber = 1;
    while ($row = mysql_fetch_row($result)) {
       $col = 'A';
       foreach($row as $cell) {
          $objPHPExcel->getActiveSheet()->setCellValue($col.$rowNumber,$cell);
          $col++;
       }
       $rowNumber++;
   }
   // Save as an Excel BIFF (xls) file
   $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');

   header('Content-Type: application/vnd.ms-excel');
   header('Content-Disposition: attachment;filename="myFile.xls"');
   header('Cache-Control: max-age=0');

   $objWriter->save('php://output');
   exit();
}
echo 'a problem has occurred... no data retrieved from the database';

EDIT 2

Alternative:

// Loop through the result set
$rowNumber = 1;
while ($row = mysql_fetch_row($result)) {
    $objPHPExcel->getActiveSheet()->fromArray(array($row),NULL,'A'.$rowNumber++);
}

should also fix this error

EDIT #3

To add a heading row.

$rowNumber = 1;
$headings = array('Name','EMail','Phone');
$objPHPExcel->getActiveSheet()->fromArray(array($headings),NULL,'A'.$rowNumber);

$rowNumber++

// Loop through the result set
while ($row = mysql_fetch_row($result)) {
   $col = 'A';
   foreach($row as $cell) {
      $objPHPExcel->getActiveSheet()->setCellValue($col.$rowNumber,$cell);
      $col++;
   }
   $rowNumber++;
}

PHPExcel Warning/Error when opening document

I've had the same problem and i resolved simply putting an

exit();

justafter the $objWriter->save('php://output'); command.

Eg.

// Redirect output to a client’s web browser (Excel2007)
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="industrializzazione_RTW_'.$rows[0]['stagione'].'.xlsx"');
header('Cache-Control: max-age=0');

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007'); 
$objWriter->save('php://output'); 
exit();
