About

Zend Framework 2 is an open source framework for developing web applications and services
using PHP 5.3+. Zend Framework 2 uses 100% object-oriented
code and utilises most of the new features of PHP 5.3, namely namespaces, late static binding,
lambda functions and closures.

Zend Framework 2 evolved from Zend Framework 1, a successful PHP framework with over
15 million downloads.

The component structure of Zend Framework 2 is unique; each component is designed with few
dependencies on other components. ZF2 follows the SOLID object oriented design principle.
This loosely coupled architecture allows developers to use whichever components they want.
We call this a “use-at-will” design. We support Pyrus
and Composer as installation and dependency tracking
mechanisms for the framework as a whole and for each component, further enhancing this design.

We use PHPUnit to test our code and Travis CI as a Continuous Integration service.

While they can be used separately, Zend Framework 2 components in the standard library form a
powerful and extensible web application framework when combined. Also, it offers a robust, high
performance MVC implementation, a database abstraction that is simple to use, and a forms component
that implements HTML5 form rendering, validation, and filtering so that developers can consolidate all
of these operations using one easy-to-use, object oriented interface. Other components, such as
Zend\Authentication and Zend\Permissions\Acl, provide user authentication and authorization against all
common credential stores.

Still others, with the ZendService namespace, implement client libraries to simply access the most
popular web services available. Whatever your application needs are, you’re likely to find a Zend
Framework 2 component that can be used to dramatically reduce development time with a thoroughly
tested foundation.

The principal sponsor of the project ‘Zend Framework 2’ is Zend Technologies,
but many companies have contributed components or significant features to the framework.
Companies such as Google, Microsoft,
and StrikeIron have partnered with Zend to provide interfaces to web
services and other technologies they wish to make available to Zend Framework 2 developers.

Zend Framework 2 could not deliver and support all of these features without the help of the vibrant
Zend Framework 2 community. Community members, including contributors, make themselves available on
mailing lists,
IRC channels and other forums.
Whatever question you have about Zend Framework 2, the community is always available to address it.
