Question

I am trying to export CSV using PHP. But instead of printing the result it’s printing Resource id #26 in the generated CSV FILE. If I remove exit from end it print’s my whole HTML page content. My code is…

      if (isset($_REQUEST['download']) && ($_REQUEST['download'] == "yes")) {
            header('Content-Type: text/csv; charset=utf-8');
            header('Content-Disposition: attachment; filename=link_point_report.csv');
            $output = fopen('php://memory', 'w+');
            fputcsv($output, array('Member Id', 'Customer Name', 'Customer Email'));

            $customerListAll = $oAdmFun->linkpoint_check_customer('', '');       
             $oAdmFun->pr($customerListAll, true);
//                if (count($customerListAll) > 0) {
//                        for ($c = 0; $c < count($customerListAll); $c++) {
//                                fputcsv($output, array('Sankalp', 'Sankalp', 'Sankalp'));
//                        }
//                }

            ob_clean();
            flush();
            exit($output);
    }

That’s because $output is a resource, which is what fopen() returns. You need to use fread() to get its contents.

EDIT: Now I understand what you were asking. To output the contents of your CSV, you need to get the text output from the resource:

rewind( $output );
$csv_output = stream_get_contents( $output );
fclose( $output );
die( $csv_output );

And it’s also a good idea to set the content-length header so that the client knows what to expect:

header('Content-Length: ' . strlen($csv_output) );
