How to retrieve data from excel file using symfony2 excelbundle? - php

Question

For a school project, I have to collect data from an Excel file uploaded by the user. I am using Symfony2 and have installed a bundle I found on knpbundles, named ExcelBundle. I read that to collect data with it from an Excel file, I should use the createWriter method of my phpExcel object. That is what I have done as shown below.
public function addContactsFromExcelAction(Request $request) {
$uploadDir = '/var/www'.$request->getBasePath().'/uploads/';
//die(var_dump($uploadDir));
$file = $request->files->get('fichierExcel');
$fileName = $file->getClientOriginalName();
$fileSaved = $file->move($uploadDir,$fileName);
$phpExcelObject = $this->get('phpexcel')->createPHPExcelObject($uploadDir.$fileName);
$writer = $this->get('phpexcel')->createWriter($phpExcelObject, 'Excel2007');
}
But the thing is that actually, I do not really know how to use the writer to collect data from the cells of my excel datasheets.
Please, could anyone give me the trick to achieve my goal ?

You can iterate as this Example:
public function xlsAction()
{
$filenames = "your-file-name";
$phpExcelObject = $this->get('phpexcel')->createPHPExcelObject($filenames);
foreach ($phpExcelObject ->getWorksheetIterator() as $worksheet) {
echo 'Worksheet - ' , $worksheet->getTitle();
foreach ($worksheet->getRowIterator() as $row) {
echo ' Row number - ' , $row->getRowIndex();
$cellIterator = $row->getCellIterator();
$cellIterator->setIterateOnlyExistingCells(false); // Loop all cells, even if it is not set
foreach ($cellIterator as $cell) {
if (!is_null($cell)) {
echo ' Cell - ' , $cell->getCoordinate() , ' - ' , $cell->getCalculatedValue();
}
}
}
}
}
