Silverstripe Framework
Besides a powerful and intuitive content authoring application, the Silverstripe CMS contains a powerful PHP5-based programming framework. The Silverstripe Framework brings immense flexibility and ease in customising your site and provides fundamentals such as security models, workflow, caching as well as multiple language and sub-site support.
Under the hood
Behind the clean CMS and website presentation sits Silverstripe Framework. Website developers use the framework to write code to create templates, logic and tailor how the CMS works. Developers get the power and flexibility of (object oriented PHP 5.3+) code, designers get the freedom of HTML5 and CSS, and content authors get the simplicity of a tailored CMS.
