$filename = "testing-exports.csv";

    header("Content-type: text/csv");
    header("Content-Disposition: attachment; filename=$filename");
    header("Pragma: no-cache");
    header("Expires: 0");

    $insquery = "SELECT username FROM r_institution where status=1";
    //$exportstmt = $conn->query($insquery);
    $insresults = $conn->query($insquery);
    //$insresults = mysqli_fetch_assoc($exportstmt);
    foreach ($insresults as $rs) {
        $row = array();
        $row[] = stripslashes($rs["username"]);
        $content[] = $row;
    }
    $content = array();
    $title = array("Institution Emails");
    foreach ($insresults as $rs) {
        $row = array();
        $row[] = stripslashes($rs["username"]);
        $content[] = $row;
    }
    $output = fopen('php://output', 'w');
    fputcsv($output, $title);
    foreach ($content as $con) {
        fputcsv($output, $con);
    }
