yii phpexcel file reader no response - yii

Question

I have a piece of code that is
$excelFile = '/tmp/sheet.xls' ;
Yii::import('application.vendors.PHPExcel',true);
$inputFileType = PHPExcel_IOFactory::identify($excelFile);
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
$objPHPExcel = $objReader->load($excelFile);
$objWorkSheet = $objPHPExcel->getActiveSheet();
$highestRow = $objWorkSheet->getHighestRow();
$hightestColumn = $objWorkSheet->getHightestColumn();
$hightestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
echo '<table>'."\n" ;
for($row=2; $row<$highestRow ; ++$row){
echo '<tr>'."\n" ;
for($col=0; $col < $highestColumnIndex ; ++$col){
echo '<td>'.$objWorksheet->getCellByColumnAndRow($col,$row)->getValue().'</td>'."\n";
}
echo '</tr>'."\n" ;
}
echo '</table>'."\n" ;
But when this code execute I do not get any file display. I also tried to put debugs to check where it failed, I could localize the error to getActiveSheet.
Any help would be appreciated
Thanks

Answer 1

Try import PHPExcel like this:
spl_autoload_unregister(array('YiiBase', 'autoload'));
Yii::import('application.vendors.PHPExcel', true);
$this->objPHPExcel = new PHPExcel();
spl_autoload_register(array('YiiBase', 'autoload'));

Here is how i display the imported excel file and works:
spl_autoload_unregister(array('YiiBase','autoload'));
Yii::import("application.vendors.phpexcel.Classes.PHPExcel", true);
$inputFileType = PHPExcel_IOFactory::identify($path);
$objReader = PHPExcel_IOFactory::createReader($inputFileType); //Excel5);
$objPHPExcel = $objReader->load($path);
spl_autoload_register(array('YiiBase','autoload'));
foreach ($objPHPExcel->getWorksheetIterator() as $worksheet) {
foreach ($worksheet->getRowIterator() as $row) {
$rowIndex=$row->getRowIndex();
$cellIterator = $row->getCellIterator();
$cellIterator->setIterateOnlyExistingCells(false); // Loop all cells, even if it is not set
foreach ($cellIterator as $cellIndex=>$cell) {
if (!is_null($cell)) {
if($rowIndex >1 && $cellIndex<=55){
$cellVal=$cell->getCalculatedValue();
echo $cellVal;
}
}
}
}
}
