dompdf save file in directory just using IDE

Question

I’m having some doubts regarding dompdf, I would like to know how to save the pdf file directly by the IDE without the need to use a browser, besides I would like to generate a loop to generate several independent pdfs, each with its specific information.

    $dompdf = new DOMPDF();
$html = "<p>Este é um teste</p>";
$dompdf->loadHtml($html);
$papel = array(0, 0, 595.28, 841.89);
$dompdf->set_paper( 'A4', 'portrait');
$dompdf -> render();
$data_salvar  = date_create();
$nome_arquivo = date_timestamp_get($data_salvar);
$nomeFinal = $nome_arquivo.".pdf";
$output = $dompdf->output();
$arquivo = "relatorios_gerados/".$nome_arquivo.".pdf";
if(file_put_contents($arquivo,$output) <> false) {
    // Define o caminho onde será salvo
    $dompdf->stream("C:\wamp64\www\geraDoc\DocumentosGerados", array ( "Attachment" => false ));

when run in the IDE I get the return
