调用未定义的方法Barryvdh \\ DomPDF \\ PDF :: setOptions（）（laravel 5.3）

Question

I follow this : How to get page number on dompdf PDF when using "view"

I add $pdf->setOptions('isPhpEnabled', true); is like this :

public function listdata()
{
    $data = User::all();

    $pdf=PDF::loadView('print_tests.test_pdf', ['data' => $data]);
    $pdf->setOptions('isPhpEnabled', true);
    $pdf->setPaper('L', 'landscape');
    return $pdf->stream('test_pdf.pdf');
}

In body (View) I add like this :

<script type="text/php">
    if ( isset($pdf) ) {
        $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>

There is exist error like this :

FatalThrowableError in PrintTestController.php line 21: Call to undefined method Barryvdh\DomPDF\PDF::setOptions()

I try change to be like ths : $pdf->set_options('isPhpEnabled', true);

It's not working too

Note :

I using barryvdh/laravel-dompdf": "^0.7.0" (v0.7)

Is there any people who can help to me?

UPDATE

I try again like this :

use Dompdf\Dompdf;

public function listdata()
{
    $data = User::all();

    $pdf = new Dompdf();
    $pdf->set_option("isPhpEnabled", true);

    $pdf=PDF::loadView('print_tests.test_pdf', ['data' => $data]);
    $pdf->setPaper('L', 'landscape');
    return $pdf->stream('test_pdf.pdf');
}

No error, but page number invisible

You may want to stop using 3 1/2-year old questions and answers, and start using the documentation provided by the developer !

There is a function Dompdf::set_option() you are probably looking for.
