Well. you may try this, it'll work if your result is not empty

public function export_to_csv($result)
{
    if(!$result) return false;
    ob_end_clean();
    header( 'Content-Type: text/csv' );
    header( 'Content-Disposition: attachment;filename=pedidos.csv');
    $fp = fopen('php://output', 'w');
    $headrow = $result[0];
    fputcsv($fp, array_keys($headrow));
    foreach ($result as $data) {
        fputcsv($fp, $data);
    }
    fclose($fp);
    $contLength = ob_get_length();
    header( 'Content-Length: '.$contLength);
}
