CodeIgniter Q & A


How to create a new CodeIgniter project?

Creating a new CodeIgniter project is a straightforward process, and I’ll guide you through the steps involved. CodeIgniter’s simplicity and ease of use make it a great choice for web development projects. Here’s how you can start a new CodeIgniter project:

  1. Download and Extract CodeIgniter: Begin by downloading the latest version of CodeIgniter from the official website ( Once the download is complete, extract the contents of the compressed archive to a directory on your web server. This directory will serve as the root of your CodeIgniter project.


  1. Configure the Database: CodeIgniter relies on a database to store and retrieve data for your application. Open the `application/config/database.php` file and configure your database connection settings, including the database type, hostname, username, password, and database name.


  1. Set the Base URL: In the `application/config/config.php` file, set the `base_url` to match the URL of your CodeIgniter project. This is important for generating proper links and URLs in your application.


  1. Optional: URL Rewriting (Clean URLs): If you want to remove “index.php” from your URLs for a cleaner look, you can enable URL rewriting. Create or modify the `.htaccess` file in your project’s root directory (if you’re using Apache) or configure your web server to handle clean URLs.


  1. Create Controllers, Models, and Views: CodeIgniter follows the Model-View-Controller (MVC) pattern, which helps organize your code. Create your controllers in the `application/controllers` directory, models in the `application/models` directory, and views in the `application/views` directory. You can also create subdirectories within these folders to organize your code effectively.


  1. Define Routes: In the `application/config/routes.php` file, you can define custom URL routes to map specific URLs to controller methods. This gives you control over how URLs are handled in your application.


  1. Start Developing: With the initial setup complete, you’re ready to start building your web application. CodeIgniter provides a wide range of libraries and helpers to assist you with common tasks like form validation, database operations, and more. Refer to the official documentation and tutorials to explore the framework’s capabilities and best practices for development.

By following these steps, you’ll have a new CodeIgniter project up and running, ready for you to develop and customize according to your specific requirements. Enjoy the flexibility and efficiency that CodeIgniter offers for building web applications.
