PHPExcel - creating multiple sheets by iteration

Question

I'm trying to create multiple sheets by iteration in phpexcel:

$i=0;

while ($i < 10) {

// Add new sheet
$objWorkSheet = $objPHPExcel->createSheet();

//  Attach the newly-cloned sheet to the $objPHPExcel workbook
$objPHPExcel->addSheet($objWorkSheet);

// Add some data
$objPHPExcel->setActiveSheetIndex($i);

$sheet = $objPHPExcel->getActiveSheet();

$sheet->setCellValue('A1', 'Hello'.$i)
        ->setCellValue('B2', 'world!')
        ->setCellValue('C1', 'Hello')
        ->setCellValue('D2', 'world!');

// Rename sheet
$sheet->setTitle($i);

$i++;
}

Unfortunately this doesn't work. I only get some sheets of this iteration filled with data and renamed and about the half are empty.

So this is the result (sheet titles):

0, 2, 4, 6, 8, 9, and 5 empty sheets

I can't figure out why only even numbered (and sheet 9) are correct in the result.

You dont need call addSheet() method. After creating sheet, it already add to excel. Here i fixed some codes:

    //First sheet
    $sheet = $objPHPExcel->getActiveSheet();

    //Start adding next sheets
    $i=0;
    while ($i < 10) {

      // Add new sheet
      $objWorkSheet = $objPHPExcel->createSheet($i); //Setting index when creating

      //Write cells
      $objWorkSheet->setCellValue('A1', 'Hello'.$i)
                   ->setCellValue('B2', 'world!')
                   ->setCellValue('C1', 'Hello')
                   ->setCellValue('D2', 'world!');

      // Rename sheet
      $objWorkSheet->setTitle("$i");

      $i++;
    }
