Zend Framework (ZF) is an open source, object-oriented web application framework implemented in PHP 5 and
licensed under the New BSD License. [1]
History
Zend Framework was conceived in early 2005 while many new frameworks, such as Ruby on Rails and the Spring
Framework, were gaining popularity in the web development community. ZF was publicly announced at the first
Zend Conference in October 2005. [2]
On July 1, 2007, Zend Framework 1.0 was released. [3]
Philosophy
ZF is a use-at-will framework. There is no single development paradigm or pattern that all Zend Framework users
must follow, although ZF does provide components for the MVC, Table Data Gateway, and Row Data Gateway
design patterns. Zend Framework provides individual components for many other common requirements in web
application development. [1]
Zend Framework also seeks to promote web development best practices in the PHP community; conventions are not
as commonly used in ZF as in many other frameworks, rather suggestions are put forth by setting reasonable defaults
that can be overridden for each ZF application’s specific requirements. [4]
Licensing
Zend Framework is licensed under the Open Source Initiative (OSI)-approved New BSD License, and all code
contributors must sign a Contributor License Agreement (CLA) based on the Apache Software Foundation’s CLA.
The licensing and contribution policies were established to prevent intellectual property issues for commercial ZF
users, according to Zend's Andi Gutmans [5] .
Sponsor and partners
Zend Technologies, co-founded by PHP core contributors Andi Gutmans and Zeev Suraski, is the corporate sponsor
of Zend Framework. [6] Technology partners include IBM [7] , Google [8] , Microsoft [9] , Adobe Systems [10] , and
StrikeIron [11] .
