I'm having problems generating a pdf from php with DOMPDF.

This is the error that gives me

Uncaught exception 'Dompdf \ Exception' with message 'No block-level parent found.

And this is the code I use:

require_once 'dompdf/autoload.inc.php';
use Dompdf\Dompdf;
// instantiate and use the dompdf class

$dompdf = new Dompdf();
$file=file_get_contents('resultados.php');
$dompdf->load_html($file);

// (Optional) Setup the paper size and orientation
$dompdf->set_paper('A4', 'landscape');

// Render the HTML as PDF
$dompdf->render();

// Output the generated PDF to Browser
$dompdf->stream('document.pdf');
echo $file;?>

I have done a print of $ file and I have observed that file_get_contents () does not process the variables. I think that there may be the error. Does anyone know any way to solve this?

Thanks in advance

Considering that the redirects are fine and that the .php file what it does is render the view to create the structure we can do this:

<?php
require_once 'dompdf/autoload.inc.php';
use Dompdf\Dompdf;
$dompdf = new Dompdf();

ob_start(); //iniciamos un output buffer
require_once('resultados.php'); // llamamos el archivo que se supone contiene el html y dejamoso que se renderize
$dompdf->load_html(ob_get_clean());//y ponemos todo lo que se capturo con ob_start() para que sea capturado por DOMPDF

$dompdf->set_paper('A4', 'landscape');
$dompdf->render();
$dompdf->stream('document.pdf');
?>
