How do I enable debug on dompdf library?

Question

I am using dompdf library to output some reports. I got a file outputing but I am having some strange behavior. How do I enable debug reporting in dompdf?

  $dompdf = new Dompdf();

  // something like this
  $dompdf->enableDebug();

  $dompdf->loadHtml($template);
  $dompdf->setBasePath(realpath('./'));
  $dompdf->render();
  $dompdf->stream('note');

Set up the globals like BrianS says:

global $_dompdf_warnings;
$_dompdf_warnings = array();
global $_dompdf_show_warnings;
$_dompdf_show_warnings = true;

Then, instead of streaming the pdf to the browser, dump the warnings array:

header('Content-type: text/plain');
var_dump($_dompdf_warnings);
die();
