Snappy
Snappy is a PHP library allowing thumbnail, snapshot or PDF generation from a url or a html page. It uses the excellent webkit-based wkhtmltopdf and wkhtmltoimage available on OSX, linux, windows.
You will have to download wkhtmltopdf 0.12.x in order to use Snappy.
Please, check FAQ before opening a new issue. Snappy is a tiny wrapper around wkhtmltox, so lots of issues are already answered, resolved or wkhtmltox ones.

$snappy = new Pdf($myProjectDirectory . '/vendor/h4cc/wkhtmltopdf-amd64/bin/wkhtmltopdf-amd64');N.B. These static binaries are extracted from Debian7 packages, so it might not be compatible with non-debian based linux distros
Some use cases

<?php
$snappy = new Pdf('/path/to/binary');
$snappy->setOption('toc', true);
$snappy->setOption('xsl-style-sheet', 'http://path/to/stylesheet.xsl') //or local file;
$snappy->generateFromHtml('<p>Some content</p>', 'test.pdf');Bugs & Support
