ExampleThis example allows to enter some HTML code in a form and generate the corresponding PDF:
<?php
//HTML2PDF by Clément Lavoillotte
include_once('html2pdf.php');
if(isset($html))
{
$pdf=new PDF();
$pdf->Open();
$pdf->SetCreator("HTML2PDF");
$pdf->SetTitle($title);
$pdf->SetSubject($subject);
$pdf->SetAuthor($author);
$pdf->SetFont('Arial', '', 12);
$pdf->AddPage();
if(ini_get('magic_quotes_gpc')=='1')
$html=stripslashes($html);
$pdf->WriteHTML($html);
//save and redirect
$pdf->Output('test.pdf');
header('Location: test.pdf');
exit;
}
?>
