Append data to existing file PHPExcel


Creating a new export file with PhpExcel library seems very easy, but when I try to open an existing excel file and write in that file I have problems, can anyone help me on this matter?

$xls = PHPExcel_IOFactory::load($download.'/'.$this->getFileName());


//add data to the file


$objWriter = PHPExcel_IOFactory::createWriter($xls, 'Excel5');


The error that I receive is an exception that is raised I suppose but I can not get the whole error to be displayed because of the unregister command that we need to call before initializing a PHPExcel object.

Therefore the error that I get is CExpection class is not found, but due to debugging I found out that the problem comes from this line:


I have checked and the $download.’/’.$this->getFileName() has the correct value.

Thank you in advance for your help.


paste whatever error is displayed
