Symphony is a web-based content management system (CMS) that enables users to create and manage websites and web applications of all shapes and sizes—from the simplest of blogs to bustling news sites and feature-packed social networks. With Symphony, you can build just about anything, and that’s what sets it apart from most other CMSs. Instead of making all kinds of assumptions about your content and what you’ll be doing with it, Symphony gives you the tools to make those decisions for yourself.
The X11/MIT licensed, PHP-driven CMS for the LAMP Stack is something worth to check out because of it’s simplicity and thoughtfulness in Design and Architecture. I even write about it here on my blog even before the PIWI Framework which is somehow near to it.
