Zend framework
Zend Framework is a group of PHP written classes. Zend offers a range of standard tools to accelerate the development of Web applications. Zend perfectly responds to the problems generated by customized application development. If your project does not fit in a CMS framework as Drupal, it’s highly likely that you will have to choose Zend. The biggest Zend competitor is Java.
The creation of a web application or a web site with Zend prevents the reinvention of the wheel. Zend offers all the necessary basic tools for good quality programming. Implementation of the MVC model (Model-View-Controller), management of authentication and of rights, localization and internationalization and data access layers; all the tools most frequently used, whatever your application is.
A large number of frameworks based on PHP, CakePHP, CodeIgniter, Simfony and even on Drupal are available. However, Zend remains for us the strongest solution thanks to its flexibility. In fact, and contrary to many other frameworks, Zend is not monolithic and even if it imposes a certain amount of rules, it remains modular.
