What is CodeIgniter? You spend a lot of time writing the same code over and again when developing a web application. Frameworks provide you a place to start and reduce the amount of code you'll need to create a website. CodeIgniter is a PHP-based framework, however it is not a PHP replacement. You don't have to abandon PHP just because you're learning CodeIgniter. PHP is a server-side scripting language that may be used to create dynamic web applications. CodeIgniter includes libraries, a clear interface, and a logical structure for accessing these libraries, as well as plug-ins, helpers, and other resources that make it easier to solve difficult PHP functions while retaining high performance.
