Go to the official CodeIgniter website (https://codeigniter.com) and navigate to the "Downloads" page. There you will find the latest version of CodeIgniter available for download. Click on the download button to save the compressed file (.zip) to your local machine.
Once the download is complete, unzip the CodeIgniter package. You will find a folder named codeigniter-x.x.x. Rename this folder to a convenient name for your project, such as myproject.
Next, you need to move the myproject folder to your web server's document root directory. The location of the document root varies depending on your operating system and web server configuration.
For example, on Apache, the document root directory might be /var/www/html, while on Nginx, it could be /usr/share/nginx/html. Consult your web server's documentation to determine the correct location.
Open the application/config/config.php file within the CodeIgniter folder using a text editor. Look for the $config['base_url'] line and set the value to the URL where your CodeIgniter application will run. For instance, if your application will run at http://localhost/myproject/, set the base URL as follows:
