In this tutorial, we are going to install CodeIgniter on Ubuntu 26.04. CodeIgniter is a lightweight PHP framework designed to help developers build web applications faster and with cleaner code. It follows the MVC (Model-View-Controller) structure, which separates application logic from presentation, making projects easier to manage and scale. Developers often use it for creating dynamic websites, business platforms, APIs, and content management systems. One reason it became popular is its speed, small footprint, and simple setup compared to heavier frameworks. It also includes built-in tools for database handling, security, session management, and form validation, helping developers focus on building features rather than writing repetitive code from scratch each time.
Installing CodeIgniter on Ubuntu 26.04 is a straightforward process that typically takes around 10 minutes. Let’s get started!
