How to install or setup CodeIgniter 3 In localhost

To install CodeIgniter 3 on your localhost, you can follow these steps:

1. Download CodeIgniter: Go to the CodeIgniter website and download the latest version of CodeIgniter 3.x. Extract the downloaded zip file to a location on your computer.
2. Place files in localhost directory: Move the extracted files to your localhost directory. If you’re using XAMPP, WAMP, or MAMP, this directory is usually htdocs for XAMPP and www for WAMP or MAMP. For other servers, it might be different.
3. Configure database settings (if required): If your CodeIgniter application will use a database, you need to set up your database configuration. Navigate to application/config/database.php and update the database settings according to your localhost environment (database hostname, username, password, database name).
4. Set up base URL (optional): Open application/config/config.php and set the base URL according to your localhost setup. By default, it’s usually set to $config['base_url'] = '';.
5. Test installation: Open your web browser and navigate to http://localhost/your_project_folder where your_project_folder is the directory where you placed the CodeIgniter files. If everything is set up correctly, you should see the CodeIgniter welcome page.

That’s it! You’ve successfully installed CodeIgniter 3 on your localhost. Now you can start building your application using CodeIgniter.
