dompdf php to pdf

Question

I’m using the DomPDF to generate the pdf. The point is that I can’t convert my html to pdf. My html is generated by several lines of php with variables and etc...

I already tried passing a variable with everything to the DomPDF::loadhtml, but since there are so many lines of code,.

Is there any way to generate the final html and move to the variable ?

// include autoloader
require_once 'dompdf/autoload.inc.php';

// reference the Dompdf namespace
use Dompdf\Dompdf;

// instantiate and use the dompdf class
$dompdf = new Dompdf();
$dompdf->loadHtml('hello world');

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

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

// Get the generated PDF file contents
$pdf = $dompdf->output();

// Output the generated PDF to Browser
$dompdf->stream();

Hello you can wear so:

$html = file_get_contents('http://www.seusite.com.br/seu_html_gigante.php');

require_once 'dompdf/autoload.inc.php';

use Dompdf\Dompdf;

$dompdf = new Dompdf();
$dompdf->loadHtml($html);
$dompdf->setPaper('A4', 'landscape');
$dompdf->render();
$pdf = $dompdf->output();
$dompdf->stream();

header('Content-type: application/pdf; charset=utf-8');
echo $pdf;

If you have problems with Session or something, consider using this other way:

ob_start();

include_once ("seu_html_gigante.php");

$html = ob_get_contents();

ob_end_clean()

require_once 'dompdf/autoload.inc.php';

use Dompdf\Dompdf;

$dompdf = new Dompdf();
$dompdf->loadHtml($html);
$dompdf->setPaper('A4', 'landscape');
$dompdf->render();
$pdf = $dompdf->output();
$dompdf->stream();

header('Content-type: application/pdf; charset=utf-8');
echo $pdf;

Answer 2

Yes, there is. The way I know to "get the final html" is to give a include and capture it in output buffer.

Example:

ob_start();

include 'seu_html_gigante.php';

$dompdf->loadHtml(ob_get_clean());
