How to add page number for every page in laravel dompdf?

I get from here : https://github.com/barryvdh/laravel-dompdf

My controller is like this :

public function listdata()
{
    $pdf=PDF::loadView('print_tests.test_pdf');
    $pdf->setPaper('L', 'landscape');
    return $pdf->stream('test_pdf.pdf');
}

My view is like this :

<table>
    <tr>
        <th>header1</th>
        <th>header2</th>
        <th>header3</th>
    </tr>
    <tr>
        <td>content-row-1</td>
        <td>content-row-1</td>
        <td>content-row-1</td>
    </tr>
    <tr>
        <td>content-row-2</td>
        <td>content-row-2</td>
        <td>content-row-2</td>
    </tr>
</table>

I want every page there is a page number

Is there any people who can help me?

Follow below steps to achieve it:
- Enable DOMPDF_ENABLE_PHP from /config/dompdf.php
- Publish vendor file via php artisan vendor:publish command
- Pass $pdf object from controller:
- Add below code inside the view file:

<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>
