CodeIgniter Interview Questions and Answers

CodeIgniter Interview Questions and Answers

CodeIgniter is an open source PHP driven framework but it’s not a PHP substitute. Diving into CodeIgniter doesn’t mean you are leaving PHP behind. PHP is a server-side scripting language for building dynamic web-based applications.

CodeIgniter contains libraries, simple interface and logical structure to access these libraries, plug-ins, helpers and some other resources which solve the complex functions of PHP more easily maintaining a high performance. It simplifies the PHP code and brings out a fully interactive, dynamic website at a much shorter time.

CodeIgniter is loosely based on the popular model–view–controller (MVC) development pattern. While controller classes are a necessary part of development under CodeIgniter, models and views are optional. Codeigniter can be also modified to use Hierarchical Model View Controller (HMVC) which allows developers to maintain modular grouping of Controller, Models and View arranged in a sub-directory format.

The first public version of CodeIgniter was released by EllisLab on February 28, 2006. Codeigniter was launched just a year after the introduction of CakePHP. Like Cake it has gained many followers in quick succession. Current version is 3.1.9 (June 12, 2018).
