我正在尝试使用PHPExcel 1.7.8 + CodeIgniter 2.1.3导出XLS文件

我已经按照PHPExcel的所有说明进行操作

但我收到这个错误:

无法加载请求的类: iofactory

这是我的控制器代码:

    //expoxt to excel all admin data
function export_excel_admin()
{
    //$data['resultsadmin'] = $this->admin_model->get_all_data_admin();
    //var_dump($data['resultsadmin']);
    //$this->load->view('administrator/export_excel/export_excel_admin', $data);
    $query = $this->db->get('tbl_admin');

    if(!$query)
        return false;

    // Starting the PHPExcel library
    $this->load->library('excel');
    $this->load->library('PHPexcel/IOFactory');

    $objPHPExcel = new PHPExcel();
    $objPHPExcel->getProperties()->setTitle("export")->setDescription("none");

    $objPHPExcel->setActiveSheetIndex(0);

    // Field names in the first row
    $fields = $query->list_fields();
    $col = 0;
    foreach ($fields as $field)
    {
        $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, 1, $field);
        $col++;
    }

    // Fetching the table data
    $row = 2;
    foreach($query->result() as …

我是C++的新手,并尝试弄清楚这行代码的含义:

cur_rect = cv::Rect(cur_rect) & cv::Rect(0, 0, mat->cols, mat->rows); // here
if( cv::Rect(cur_rect) == cv::Rect() )  //here
{
.......
}
