In the 0.6.0 code you will be able to use HTML+CSS to generate headers and footers. There are a few limitations when compared to using inline PHP (e.g. no PAGE_COUNT placeholder yet), so whether or not this is viable depends on your needs.

The following code will produce a two-page document with a header and footer:

<html>
<head>
  <style>
    @page { margin: 180px 50px; }
    #header { position: fixed; left: 0px; top: -180px; right: 0px; height: 150px; background-color: orange; text-align: center; }
    #footer { position: fixed; left: 0px; bottom: -180px; right: 0px; height: 150px; background-color: lightblue; }
    #footer .page:after { content: counter(page, upper-roman); }
  </style>
<body>
  <div id="header">
    <h1>Widgets Express</h1>
  </div>
  <div id="footer">
    <p class="page">Page </p>
  </div>
  <div id="content">
    <p>the first page</p>
    <p style="page-break-before: always;">the second page</p>
  </div>
</body>
</html>

You could also use a combination of the two styles if you needed access to some of the missing functionality. PDF objects and text added using the page_text method render on top of the HTML content.

There is a FAQ entry on the DOMPDF wiki: Is there a way to add headers and footers or page numbers?.

So you can either add the following "inline PHP"-snippet to your HTML-input (add a similar page_text-call for your footer):
```
<script type="text/php">
    if ( isset($pdf) ) {
        $font = Font_Metrics::get_font("helvetica", "bold");
        $pdf->page_text(72, 18, "Header: {PAGE_NUM} of {PAGE_COUNT}",
                        $font, 6, array(0,0,0));
    }
</script>    
```
If you rather want to implement this on your caller-side (meaning in the PHP code directly) you have to call the DOMPDFS's get_canvas()-method which returns the underlying PDF-Renderer which allows you to call the page_text method like in the example above. Let me show you what I mean:
```
// your dompdf setup        
$dompdf = new DOMPDF();

$dompdf->load_html($html);
$dompdf->render();

// add the header
$canvas = $dompdf->get_canvas();
$font = Font_Metrics::get_font("helvetica", "bold");

// the same call as in my previous example
$canvas->page_text(72, 18, "Header: {PAGE_NUM} of {PAGE_COUNT}",
                   $font, 6, array(0,0,0));
```
Eventually you have to call page_text after load_html (just try it out).

# Instanciamos un objeto de la clase DOMPDF.
$dompdf = new DOMPDF();

# Definimos el tamaño y orientación del papel que queremos.
# O por defecto cogerá el que está en el fichero de configuración.
$dompdf->set_paper("Letter", "portrait");

# Cargamos el contenido HTML.
$dompdf->load_html(utf8_decode($html));

# Renderizamos el documento PDF.
$dompdf->render();

#Esto es lo que imprime en el PDF el numero de paginas
$canvas = $dompdf->get_canvas();
$footer = $canvas->open_object();
$w = $canvas->get_width();
$h = $canvas->get_height();
$canvas->page_text($w-60,$h-28,"Página {PAGE_NUM} de {PAGE_COUNT}", Font_Metrics::get_font('helvetica'),6);
$canvas->page_text($w-590,$h-28,"El pie de p&aacute;gina del lado izquiero, Guadalajara, Jalisco C.P. XXXXX Tel. XX (XX) XXXX XXXX", Font_Metrics::get_font('helvetica'),6);

$canvas->close_object();
$canvas->add_object($footer,"all");

# Enviamos el fichero PDF al navegador.
//$dompdf->stream('FicheroEjemplo.pdf');

# Para grabar en fichero en ruta especifica
$output = $dompdf->output();
file_put_contents('ejemplo.pdf',$output);

 #Liberamos 
unset($dompdf);
