CodeIgniter is a powerful PHP framework that largely follows the observer model view controller (MTVC) model. Though CodeIgniter doesn't enforce the usage of formal models, views and controller types, it does support hierarchical, multi-table and scenario-based MVC designs. CodeIgniter has an active community that answers questions and provides documentation on all aspects of the software. In addition, it includes support for XML web services, XML access to the ASP and WEB service back end, as well as support for various databases such as Oracle, Pervasive SQL, MSSQL, MySQL, and Sybase.
CodeIgniter has similarities with several other well known web frameworks such as CakePHP, Joomla and ZenCart. However, it differs from other frameworks in that it is built upon the open source Open semantic framework (OSF), which is an evolution of PHP's very famous meta tag language (XML). This newer version of OSF brings significant enhancements and enables the developers to create applications that will run in any environment and on any operating system. In addition to its strengths and limitations, CodeIgniter is easy to install and provides many benefits including support for Windows servers that can be extended through the use of third party tools and scripts.
With the popularity of MVC based web development on the rise, developers may wonder what is so special about the CodeIgniter framework. The answer is that, with CodeIgniter, web developers can enjoy many benefits that would otherwise be very expensive with other object-oriented frameworks such as ASP or HTML. By allowing the developer to create reusable code with an object orientation, the CodeIgniter framework allows developers to build MVC-like applications that can scale to large applications without the need for a large number of developers and can be easily maintained.
