        else{

            $data = array('upload_data' => $this->upload->data());
            $full_path = $data['upload_data']['full_path'];

            //---------Config read file content----------//
            $reader = new \PhpOffice\PhpSpreadsheet\Reader\Xlsx(); //Excel 2007 or higher
            //$reader = new \PhpOffice\PhpSpreadsheet\Reader\Xls(); //Excel 2003
            $spreadsheet = $reader->load($full_path);
            $sheetData = $spreadsheet->getActiveSheet()->toArray(null, true, true, true);
            //var_dump('<pre>');
            //var_dump($sheetData);
            $this->load->view('header_view');
            $this->load->view('menu_view');
            $this->load->view('upload_view', $sheetData);
        }
    }

}

/* End of file Upload.php */
/* Location: ./application/controllers/Upload.php */

<强>2。查看代码

<?php                       
    foreach ($sheetData as $value) {
        echo $value -> A;
    }
?>

Answer 1

试试这个方法:

$dataarr = array();    
$dataarr['sheetData'] = $spreadsheet->getActiveSheet()->toArray(null, true, true, true);

$this->load->view('header_view');
$this->load->view('menu_view');
$this->load->view('upload_view', $dataarr);

我想这对你有帮助。
