How to get page number on dompdf PDF when using "view"

If you're using DOMPDF >= 0.7.0, the dompdf_config.inc.php file has been removed and adding a page number now requires a slightly different approach:

Because the dompdf_config.inc.php file has been removed from this release (and is no longer referenced) all dompdf options should be set at run time.

To enable PHP code to be executed by DOMPDF, use:

$dompdf->set_option("isPhpEnabled", true);

Also, FontMetrics should now be called by using $fontMetrics instead of Font_Metrics, so the code mentioned by @user1231342435346354 changes slightly:

<script type="text/php">
if ( isset($pdf) ) { 
    $pdf->page_script('
        if ($PAGE_COUNT > 1) {
            $font = $fontMetrics->get_font("Arial, Helvetica, sans-serif", "normal");
            $size = 12;
            $pageText = "Page " . $PAGE_NUM . " of " . $PAGE_COUNT;
            $y = 15;
            $x = 520;
            $pdf->text($x, $y, $pageText, $font, $size);
        } 
    ');
}
</script>

Update Regarding changes with version of dompdf >= 0.7.0
1. Because the dompdf_config.inc.php file has been removed from this release (and is no longer referenced) all dompdf options should be set at run time.
4. The FontMetrics class is now instantiated instead of static. To simplify migration of embedded scripts from earlier versions of dompdf we provide access to the instantiated FontMetrics class via the $fontMetrics variable. Please update your embedded scripts. For example, FontMetrics::get_font('helvetica') would now be $fontMetrics->getFont('helvetica').
~ Thanks to Dennis Ameling's answer for the updated information.

Found my answer by looking over the dompdf_config.inc.php file. As it turns out, DOMPDF_ENABLE_PHP is set to false thus causing the inline php script to be ignored. I simply edited dompdf_config.custom.inc.php to the following and all is fine and working with the later code in the view.

In dompdf/dompdf_config.custom.inc.php

<?php
    define("DOMPDF_ENABLE_PHP", true);

At Run Time

$dompdf->set_option("isPhpEnabled", true);

Then, in my html file

<body>
    <script type="text/php">
        if ( isset($pdf) ) {
            // OLD 
            // $font = Font_Metrics::get_font("helvetica", "bold");
            // $pdf->page_text(72, 18, "{PAGE_NUM} of {PAGE_COUNT}", $font, 6, array(255,0,0));
            // v.0.7.0 and greater
            $x = 72;
            $y = 18;
            $text = "{PAGE_NUM} of {PAGE_COUNT}";
            $font = $fontMetrics->get_font("helvetica", "bold");
            $size = 6;
            $color = array(255,0,0);
            $word_space = 0.0;  //  default
            $char_space = 0.0;  //  default
            $angle = 0.0;   //  default
            $pdf->page_text($x, $y, $text, $font, $size, $color, $word_space, $char_space, $angle);
        }
    </script>
    <div

If you go this route, don't forget to restart Apache
