php - From file_put_contents to saved file on server -

i'm using google project api convert html pdf. works great , amazing. can here if want: http://code.google.com/p/dompdf/

my question follows, plugin it's magic , obtain this:

file_put_contents("nameofpdf.pdf", $pdf); 

how go saving server? i'm new saving info server, please detail bit.

thanks.

more of code here

  $dompdf = new dompdf();   $dompdf->load_html($html);   $dompdf->set_paper( "a4" , "portrait");   $dompdf->render();    $dompdf->stream("xxxxx.pdf", array("attachment" => false));    $pdf = $dompdf->output();  // can write $pdf disk, store in database or stream // client.      file_put_contents("xxxxx.pdf", $pdf); 

if read docs correctly, need remove line:

$dompdf->stream("xxxxx.pdf", array("attachment" => false)); 

it save disk without output.

to specify path, add show file name in file_put_contents call.
