  1. Try this steps

        ob_start();
    include('./some_dynamic_page.php');
    $content = ob_get_clean();

    require_once("dompdf/dompdf_config.inc.php");

    $dompdf = new DOMPDF();
    $dompdf->load_html($content);
    $dompdf->set_paper('A4', 'portrait');
    $dompdf->render();
    $dompdf->stream("result.pdf", array("Attachment" => 0));

    And the config:
    (dompdf_config.custom.inc)
