Zend Framework is an open source, object-oriented web application framework implemented in PHP 5 and licensed under the New BSD License. Zend Framework—often referred to as ZF—is developed with the goal of simplifying web development while promoting best practices in the PHP developer community.
ZF's use-at-will architecture allows developers to reuse components when and where they make sense in their applications without requiring other ZF components beyond minimal dependencies. There is therefore no single development paradigm or pattern that all Zend Framework users must follow, although ZF does provide components for the MVC and Table Gateway design patterns which are used in most ZF applications. Zend Framework provides individual components for many other common requirements in web application development, including authentication and authorization via access control lists (ACL), application configuration, data caching, filtering/validation of user-provided data for security and data integrity, internationalization, interfaces to AJAX functionality, email composition/delivery, Lucene-format search indexing and querying, and all Google Data APIs along with many other popular web services. Because of their loosely coupled design, ZF components can be used relatively easily alongside components from other PHP web application frameworks.cite web

History and philosophy

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 [http://www.zendcon.com/ Zend Conference] .cite web

The designers of Zend Framework sought to combine the ease-of-use and rapid application development (RAD) features of these new frameworks with the simplicity, openness, and real-world practicality that is highly valued in the PHP community.cite web

Typically, specific development usage scenarios are implemented using more generalized software components through automatic configuration and/or code generation. In [http://framework.zend.com/download previous releases] , the Zend Framework community has opted to complete development and testing of these underlying components before starting work on simplifying development tasks such as database migrations, generating scaffolding, and project creation and configuration. This practice has been the subject of some criticism since some functionality considered by many as necessary for a general release for modern web application frameworks is slated for future Zend Framework releases. Many ZF users, however, have found such generalized software components more reusable and extensible in implementing their applications.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.

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 [http://www.apache.org/licenses/icla.txt CLA] . The licensing and contribution policies were established to circumvent any intellectual property issues for commercial ZF users.

ponsor and partners

Zend Technologies, co-founded by PHP core contributors Andi Gutmans and Zeev Suraski, is the corporate sponsor of Zend Framework. Technology partners include IBM, Google, Microsoft, and StrikeIron.

Requirements

Zend Framework requires PHP 5.1.4 or later, although the [http://framework.zend.com/manual/en/ ZF Programmer's Reference Guide] strongly recommends PHP 5.2.3 or later for security and performance improvements included in these versions of PHP. PHPUnit 3.0 or later is required to run the unit tests shipped with Zend Framework. Many components also require PHP extensions; a full list of components and their dependencies can be found [http://framework.zend.com/manual/en/requirements.zendcomponents.html in the Programmer's Reference Guide] .

Releases

Zend Framework releases are versioned with three numbers in the format "x.y.z", where a changes in "x", "y", or "z" correspond to major, minor, and mini releases, respectively. The first General Availability release of ZF was released on 2007-06-30 as Zend Framework 1.0. The latest release is [http://framework.zend.com/download 1.6.1] , which was made available for download on 2008-09-15.

Code, documentation, and test standards

Code contributions to Zend Framework are subject to rigorous code, documentation, and test standards. All code must meet ZF’s [http://framework.zend.com/wiki/display/ZFDEV/PHP+Coding+Standard+%28draft%29 coding standards] and unit tests must reach 80% code coverage before the corresponding code may be moved to the release branch.cite web
