PHP On Pie is a PHP framework that combines the best ideas from PHP projects like Drupal, CodeIgniter, Kohana, and ZendFramework. It has very few core concepts: classes, models, events, slots, and tools. It lets you repackage completed apps into plugins that you or others can use later. Its smart database classes allow you to implement vertical and horizontal partitioning (sharding) easily to handle millions of users.
Microweber is a drag-and-drop Web content management system that makes it possible to create Web sites without any programming. You can edit text directly on the site and see the results in real-time rather than having to constantly reload the page. You can also reorder site elements and extend them using custom modules such as galleries and contact forms. Every aspect of your page’s elements can be changed, including their skin.
