           $html =file_get_contents('mpdf/test.html');
            include("../mpdf.php");

            $stylesheet = file_get_contents('assets/css/main.css');
            $mpdf->WriteHTML($stylesheet,1);    // The parameter 1 tells that this is css/style only and no body/html/text
          // LOAD a stylesheet 2
            $stylesheetextra = file_get_contents('assets/css/test.css');

You can do it just storing the CSS content in one variable, like this:

$stylesheet  = '';
$stylesheet .= file_get_contents('css/bootstrap.min.css');
$stylesheet .= file_get_contents('css/style.css');
$stylesheet .= file_get_contents('css/impressao_ctr.css');
