CodeIgniter is a lightweight PHP framework designed for programmers that require a simple and effective tool set to build full-featured web – based applications. CodeIgniter is a PHP framework for creating MVC-based web services with good performance.
Ellis Lab developed CodeIgniter, which is now a venture of the British Columbia Institute of Technology. The MVC technique for development is used by CodeIgniter (although it is very loosely based which allows for flexibility). MySQL (4.1+), MySQL i, MS SQL, Postgres, Oracle, SQLite, and ODBC are among the databases supported.
CodeIgniter includes libraries, a clear interface, and a logical organization for accessing these library functions, as well as plug-ins, utilities, as well as other assets that make it easier to solve complicated PHP operations while retaining excellent productivity. It shortens the time it takes to create a fully reactive, responsive design by simplifying the PHP code. CodeIgniter is a PHP framework, however it is not a PHP replacement. Using CodeIgniter does not imply that you are abandoning PHP. You spend much time implementing the same code over and again when developing a web service. Frameworks give you an opportunity to begin and decrease the amount of a code you’ll need to develop a website.
CodeIgniter includes libraries, a user-friendly design, and a logical framework for accessing these libraries, plug-ins, helpers, and other resources that make it easier to solve difficult PHP functions while retaining excellent speed. By reducing the PHP code, it reduces the time it takes to construct a fully responsive, dynamic website. It requires PHP 5.2.6 or newer, as well as MySQL 4.1 or newer. Furthermore, it strengthens your website and makes your code easier to read and manage. You’ll need to understand how and when to use PHP if you’re going to use CodeIgniter. Developers for CodeIgniter must be familiar with PHP, including its basic syntax and how it interacts with databases and HTML.
CodeIgniter is an architecture for constructing web pages with PHP that is built on PHP Application Development. It is a small-footprint, a concise, beautiful, and effective toolbox used by programmers who want to make complete Web Applications.
