PHP Create PDF
file on fly With PDFlib
This tutorial demos how to create a PDF file on fly with
PDFlib.
The PDF ( portable document format) file is an versatile
format for transferring a document over the Internet.
Many companies use the PDF format to transfer contracts, manuals,
and other documents over the Internet without trying to convert them
to HTML or changing the format of the document in any way.
This code will be useful
if you were considering creating invoices, reports or any other
hardcopy file for your client.
Testing PDFlib installation
This tutorial needs PdfLib properly installed. PDFlib
is available for download at http://www.pdflib.com/products/pdflib/index.html, but requires
that you purchase a license for commercial use.

Copy the following code to a file (phpinfo.php) and save it in your
web root. Then launch it like : http://your-web-site/phpinfo.php.

We use the following code to create PDF. Save the following code
as cpdfdemo.php.
<?php
if(isset($_POST['submit'])
{
$mytext=$_POST['

$pdf = pdf_new();
pdf_open_file($pdf);
pdf_begin_page($pdf, 595, 842);
pdf_set_font($pdf, "Times-Roman", 30, "host");
pdf_set_value($pdf, "textrendering", 1);
pdf_show_xy($pdf, $mytext,
50, 750);
pdf_end_page($pdf);
pdf_close($pdf);
$data = pdf_get_buffer($pdf);
header("Content-type: application/pdf");
header("Content-disposition: inline; filename=test.pdf");
