How to Install Codeigniter on a Local Server in 2025?

CodeIgniter is a popular PHP framework known for its speed, small footprint, and ease of use. As web development continues to evolve, ensuring a smooth and correct installation of CodeIgniter on your local server is essential for your project's success. In this guide, we will walk you through installing CodeIgniter on a local server in 2025.

Prerequisites

Before you begin, ensure that you have the following software and configurations ready on your local machine:

1. PHP 8.x: CodeIgniter 4.3.x (and newer) is compatible with PHP 8.x.
2. MySQL or MariaDB: A database system for managing your data.
3. Composer: A tool for dependency management in PHP.
4. Local Server Environment: XAMPP, WAMP, or MAMP—whatever suits your operating system.

Step-by-Step Installation

Step 1: Installing Composer

Composer is required to manage CodeIgniter dependencies. If you haven't installed Composer yet, download and install it from getcomposer.org.

Step 2: Setting Up the Local Server

Make sure your local server (XAMPP, WAMP, or MAMP) is up and running. For this guide, we will use XAMPP on Windows, but the steps will be similar across platforms.

1. Launch XAMPP and start Apache and MySQL modules.
2. Confirm PHP is working by running php -v in your terminal or a command prompt.

Step 3: Downloading CodeIgniter

1. Open your terminal or command prompt.
2. Navigate to the root directory of your web server, usually in htdocs (XAMPP) or www (WAMP).
3. Run the following command to install CodeIgniter using Composer:

bash composer create-project codeigniter4/appstarter my-project

Replace my-project with your desired project name.

Step 4: Configuring CodeIgniter

1. Navigate to my-project directory.
2. Open .env file and set CI_ENVIRONMENT to development.
3. Set up the base URL and database configurations in app/Config/App.php and app/Config/Database.php.

Step 5: Testing Your Installation

1. Open your web browser.
2. Go to http://localhost/my-project/public.
3. If installation is successful, you will see the CodeIgniter welcome page.
