In your PHP code, include the dompdf/autoload.inc.php file:

require_once '/home/lngspvtltd/public_html/dompdf-0.7.0/autoload.inc.php';

You can now use dompdf to generate PDFs from HTML code. Here's an example:

use Dompdf\Dompdf;

// instantiate and use the dompdf class
$dompdf = new Dompdf();
$dompdf->loadHtml('<h1>Hello, world!</h1>');
$dompdf->render();
$dompdf->stream();



NOTE:

dompdf v0.7.0 is an older version and may not have all the features and bug fixes of the latest version. It is recommended to upgrade to a newer version of PHP and dompdf if possible.
