Zend Framework 2 (ZF2) is a modern and flexible PHP framework that helps web developpers to build web applications of different complexities. The major sponsor of company Zend Framework is Zend Technologies, which makes it very strong and stable. There are two major improvments of this second version over ZF1.

Second, ZF2 implements all the features PHP5.3+ can offer particularly the namespaces. In the previous versions, a controller class is named as follows:
class IndexController extends Zend_Controller_Action
{

class IndexController extends AbstractActionController
{
}
