Some of the platforms that we use.
Drupal is a free and open-source content management framework written in PHP and distributed under the GNU General Public License. It is used as a back-end framework for about 5% of all web site worldwide ranging from personal blogs to corporate, political, and government sites. It is also used for knowledge management and business collaboration.
WordPress is a free and open-source content management system (CMS) based on PHP and MySql. WordPress is installed on a web server, which either is part of an internet hosting service or is a network host itself; the first case may be on a service like wordpress.com, for example and the second case is a computer running the software package wordpress.org. An example of the second case is a local computer configured to act as its own web server hosting WordPress for a single-user testing or learning purpose. Features include a plugin architecture and template system. WordPress is used by more than 25% of the top 10 million websites around the globe.
SilverStripe is a free and open source Content Management System (CMS) and Framework for creating and maintaining websites and web applications. It provides an out of the box web-based administration panel that enables users to make modifications to parts of the website, which includes a WYSIWYG website editor. The core of the software is SilverStripe Framework, a PHP Web application framework.
SilverStripe is released under the terms of the BSD License.
CodeIgniter is an open-source software rapid development web framework, for use in building dynamic web sites with PHP.
CodeIgniter is loosely based on the popular model–view–controller (MVC) development pattern. While controller classes are a necessary part of development under CodeIgniter, models and views are optional.
CodeIgniter is most often noted for its speed when compared to other PHP frameworks. In a critical take on PHP frameworks in general, PHP creator Rasmus Lerdorf spoke at frOSCon in August 2008, noting that he liked CodeIgniter "because it is faster, lighter and the least like a framework."
