I am using PHP Codeigniter3 MVC architecture. I am working on Export Excel package.... I followed same as your example.

I got Table data, but this data I want to be share to Excel File.

Where should I save the export.php file in Codeigniter3 MVC architecture. Either in Controllers or Reports folder.

Please give me the suggestion.

Thanks for your reply. I wrote export.php code in controller, but it gives me error as follows

Message: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\CI3\application\libraries\koolreport\core\src\KoolReport.php:455)

Filename: excel/FileHandler.php

My Controller is as follows:

public function index()
   {
   	$this->load->helper('url');
   	$this->load->database('MainiDM');
   		
   	   include APPPATH."reports\ExcelReport_Ex.php";
          $report = new ExcelReport_Ex;
          $report->run()->render();
         

         $type = isset($_GET['type'])? $_GET['type'] : 'CSV';

         if($type === 'XLSX')
         {
            $report->exportToXLSX('ExcelReportSpreadsheet')->toBrowser("ExcelReport.xlsx");
           }

         elseif($type === 'ODS')
         {
            $report->exportToODS('ExcelReportSpreadsheet')->toBrowser('ExcelReport.ods');
          }

         elseif($type === 'CSV')
         {
            $report->exportToCSV('ExcelReportSpreadsheet')->toBrowser('ExcelReport.csv');
          }

   	}
