converting php to codeigniter

Step 1: Start by creating a new file with ".php" file extension. Step 2: In your CodeIgniter application, create a new controller file and name it following the CodeIgniter naming conventions. Step 3: Inside the controller file, define a class that extends the CI_Controller class. Step 4: Create a function within the controller file that corresponds to the desired functionality. Step 5: Use CodeIgniter's URL routing to map the controller function to a specific URL. Step 6: Use CodeIgniter's view files to generate HTML content and pass data from the controller to the view. Step 7: Access the controller function by visiting the mapped URL in a web browser to see the PHP code functioning within the CodeIgniter framework.
