我试图通过codeigniter实现PHPExcel，我得到这个错误
class Users extends CI_Controller {
/**
* Index Page for this controller.
*
* Maps to the following URL
* http://example.com/index.php/welcome
* - or -
* http://example.com/index.php/welcome/index
* - or -
* Since this controller is set as the default controller in
* config/routes.php, it's displayed at http://example.com/

* So any other public methods not prefixed with an underscore will

public function _construct()
{
}
public function index()
{
$this->load->library('phpexcel');
$this->load->library('PHPExcel/iofactory');
$objPHPExcel = new PHPExcel();
$objPHPExcel->getProperties()->setTitle("title")
->setDescription("description");
// Assign cell values
$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->setCellValue('A1', 'cell value here');
// Save it as an excel 2003 file
$objWriter = IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save("nameoffile.xls");
}
}
/* End of file welcome.php */
/* Location: ./application/controllers/welcome.php */
我得到这个错误:
Fatal error: Call to private IOFactory::__construct() from context 'CI_Loader' in F:'xampp'htdocs'import'system'core'Loader.php on line 1099
类Users扩展CI_Controller {
