Answer 1

Try this example

<?php
$name = rand('0','10000').'.xlsx';
$n = rand('0','100');
error_reporting(E_ALL);
include 'PHPExcel/Classes/PHPExcel.php';
include 'PHPExcel/Classes/PHPExcel/Writer/Excel2007.php';
$o = new PHPExcel();
$o->getProperties()->setCreator('Creator');
$o->getProperties()->setLastModifiedBy('Last Modified');
$o->getProperties()->setTitle("Office 2007 XLSX Document ");
$o->getProperties()->setSubject('Subject');
$o->getProperties()->setDescription("Office 2007 XLSX, generated using PHP classes.");
$o->setActiveSheetIndex(0);
$o->getActiveSheet()->SetCellValue('A1', 'Name');
$o->getActiveSheet()->SetCellValue('B1', 'Rating');
$o->getActiveSheet()->SetCellValue('A2', 'Shawshank Redemption');
$o->getActiveSheet()->SetCellValue('B2', $n);
$o->getActiveSheet()->SetCellValue('A3', 'A Clockwork Orange');
$o->getActiveSheet()->SetCellValue('B3', $n);

$o->getActiveSheet()->setTitle('Films');

$objWriter = new PHPExcel_Writer_Excel2007($o);

$objWriter->save('excel/'.$name); // exce/ = filepath

?>

I think the problem you are having relates to the $objWriter variable.
