（内联）PHP in domPDF 7.0

Question

I switched from TCPDF to domPDF because it seems more convenient to handle when creating invoices from html to pdf (I am rather a low pro on PHP :)). Now that I created the html file as a PDF file I recognized it does not output any PHP in the PDF - since the data from my sql databanks should fill the PDF it is kinda a problem.

I saw that you can enable PHP in the options.php included in the src-folder and I tried to do like it is written in the manual (and also tried various other code lines) but it just doesn't want to work:

$root = realpath($_SERVER["DOCUMENT_ROOT"]);

require_once ("$root/../xxx/dompdf/autoload.inc.php");

use Dompdf\Dompdf;
use Dompdf\Options;

$options = new Options();
$options->setIsPhpEnabled('true');
$dompdf = new Dompdf($options);

$dompdf->loadHtml(file_get_contents("testdomhtml.php"));

$dompdf->setPaper('A4', 'portrait');

$dompdf->render();

$dompdf->stream("bla",array("Attachment"=>0));

The PDF is shown but without the input from any PHP code.

If someone would be so kind, I would also be interested in knowing why and in how far enabling PHP is a security risk since I actually want to use that for my business. Would it be more advisable to wrap it all up in the main php file without loading external html and css files?

Thanks a lot in advance!

Answer 1

You could do something like this (not tested the code). Replace

$dompdf->loadHtml(file_get_contents("testdomhtml.php"));

With

ob_start();
include 'testdomhtml.php';
$output = ob_get_clean();
$dompdf->loadHtml($output);
