CodeIgniter with PHPExcel fatal error cannot redeclare class IOFactory

Question

I\'m trying to use PHPExcel with CodeIgniter.

My problem is when i want to use this method below, I got PHP Fatal Error : Cannot redeclare class IOFactory

Answer 1

No need to write

$this->load->library('PHPExcel');

Just start with

$this->load->library('PHPExcel/IOFactory');

Edited :::

In my project I have done by these way,

Step1: in libraries\PHPExcel\Reader

Rename Excel5.php to PHPExcel_Reader_Excel5.php

Step2:

$filePath = $dir.$uploadedfile;
$objReader = $this->load->library('PHPExcel/Reader/PHPExcel_Reader_Excel5', $filePath);
$objReader = new PHPExcel_Reader_Excel5();
$objPHPExcel = $objReader->load($filePath);     
$rowIterator = $objPHPExcel->getActiveSheet()->getRowIterator();                        
$sheet = $objPHPExcel->getActiveSheet();
$maxRowIndex = $sheet->getHighestRow();
$highestColumn = $sheet->getHighestColumn();
$maxColIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
