I am creating a number of reports that I display in the browser. This one, for example, downloads some Excel workbooks to the users PC. I have decided that I also want to save the reports in S3, for later encryption and download.

Can I change ))->toBrowser($this->session->userdata('campaign') . "_workbook.xlsx"); to ALSO create a file (on the server) at the same time?

   public function audit()
    {
        $title = sprintf("Audit Workbook for %s", $this->session->userdata('campaign'));
        $description = sprintf("paramaters used by Research Study Online to build for %s", $this->session->userdata('campaign'));
        $report = new MyExportExcel;
//        $report->run()->exportToExcel()->toBrowser($this->session->userdata('campaign') . "_workbook.xlsx");
        $report->run()->exportToExcel(array(
            "properties" => array(
                "creator" => "Research Study Online",
                "title" => $title,
                "description" => $description,
                "subject" => "Audit Workpapers",
                "keywords" => "",
                "category" => "",
            )
        ))->toBrowser($this->session->userdata('campaign') . "_workbook.xlsx");

    }

I found this:

dataStore() #
After report is run, data will be stored at dataStores, you can access them with dataStore method

->dataStore(string $storeName)
Example:


$report = new MyReport;

$report->run();

$result = $report->dataStore("result");

What do you mean "you can access them"??? Is $result a path to a file?
