Creating the PDF from local HTML file.... Note that we customize the headers and footers!<br />
<?php
// Require the class
require_once dirname(__FILE__) . '/../HTML_ToPDF.php';
// Full path to the file to be converted
$htmlFile = dirname(__FILE__) . 'http://www.mynet.com';
// The default domain for images that use a relative path
// (you'll need to change the paths in the test.html page
// to an image on your server)
$defaultDomain = 'www.rustyparts.com';
// Full path to the PDF we are creating
$pdfFile = dirname(__FILE__) . '/timecard.pdf';
// Remove old one, just to make sure we are making it afresh
@unlink($pdfFile);
// Instnatiate the class with our variables
$pdf =& new HTML_ToPDF($htmlFile, $defaultDomain, $pdfFile);
// Set headers/footers
$pdf->setHeader('color', 'blue');
$pdf->setFooter('left', 'Generated by HTML_ToPDF');
$pdf->setFooter('right', '$D');
$result = $pdf->convert();
// Check if the result was an error
if (is_a($result, 'HTML_ToPDFException')) {
die($result->getMessage());
}
else {
echo "PDF file created successfully: $result";
echo '<br />Click <a href="' . basename($result) . '">here</a> to view the PDF file.';
}
?>
</body>
</html>
A more complex example. It could be used to convert this remote HTML file into this PDF file. Additionally, we set several options to customize the look.

Creating the PDF from remote web page...<br />
<?php
// Require the class
require_once dirname(__FILE__) . '/../HTML_ToPDF.php';
// Full path to the file to be converted (this time a webpage)
// change this to your own domain
$htmlFile = 'http://www.example.com/index.html';
$defaultDomain = 'www.example.com';
$pdfFile = dirname(__FILE__) . '/test2.pdf';
// Remove old one, just to make sure we are making it afresh
@unlink($pdfFile);
$pdf =& new HTML_ToPDF($htmlFile, $defaultDomain, $pdfFile);
// Set that we do not want to use the page's css
$pdf->setUseCSS(false);
// Give it our own css, in this case it will make it so
// the lines are double spaced
$pdf->setAdditionalCSS('
p {
line-height: 1.8em;
font-size: 12pt;
}');
// We want to underline links
$pdf->setUnderlineLinks(true);
// Scale the page down slightly
$pdf->setScaleFactor('.9');
// Make the page black and light
$pdf->setUseColor(false);
// Convert the file
$result = $pdf->convert();
// Check if the result was an error
if (is_a($result, 'HTML_ToPDFException')) {
die($result->getMessage());
}
else {
echo "PDF file created successfully: $result";
echo '<br />Click <a href="' . basename($result) . '">here</a> to view the PDF file';
}
?>
</body>
</html>
Finally, we create a PDF file based on a dynaically generated page. We buffer the content of the page and then create the PDF at the end. We set a number of CSS tags, including page size and margins. After creating the PDF we encrypt it (password is "foobar"). Example output can be seen here.
<?php
/** $Id: example3.php 2426 2006-11-18 19:59:26Z jrust $ */
/**
* Here we create an encrypted PDF file based on a dynaically generated page.
* We buffer the content of the page and then create the PDF at the end.
* Then we load up PDFEncryptor and set meta-data, password, and permissions.
* Finally, we send a header and the file so it opens straight into the
* browser.

// Require the class
require_once dirname(__FILE__) . '/../HTML_ToPDF.php';
require_once dirname(__FILE__) . '/../PDFEncryptor.php';

$linkToPDFFull = $linkToPDF = tempnam(dirname(__FILE__), 'PDF-');
// Remove the temporary file it creates

// Give it an extension
$linkToPDFFull .= '.pdf';
$linkToPDF .= '.pdf';

An example dynamic page that is converted to PDF on 8x14 paper,
in landscape mode, with 1.0cm margins!<br />
And what about <sub>subscript</sub> or <sup>superscript</sup>?<br />
Hmmm...one last test, special characters: α © »<br /><br />
This document has been encrypted with the helper PDFEncryptor class so you will need to
enter "foobar" for the password<br />
This should open straight into your PDF reader,
but, if not, click <a href="<?php echo $linkToPDF; ?>">here</a> to view the PDF file.<br />
<div class="noprint">This should not show up.</div>

This demonstrates the use of CSS classes for an element.<br />
