A common problem when developing a web application is having producing a high-quality PDF out of an existing layout/view/template. Perhaps for a reporting engine, an invoice, a receipt, or any number of other situations.
Well, there is. It's called wkhtmltopdf. Normally a command line utility, with the release of 0.10.0_beta5 antialize included a simple C API to be able to build bindings in other popular languages.
I'm proud to announce the release of a PHP extension that facilitates the process of doing the conversion directly in PHP:
<?php wkhtmltox_convert('pdf', array('out' => 'test.pdf', 'imageQuality' => '95'), // global settings array( array('page' => 'http://www.visionaryrenesis.com/'), array('page' => 'http://www.google.com/', 'web.printMediaType' => true) )); ?>
I'm hosting the code at GitHub: http://github.com/mreiferson/php-wkhtmltox
It was certainly interesting working with PHP under the hood but overall the process was pretty straightforward. Keep in mind the function signatures may change a bit as the API matures. Feedback welcome!
