3 minutes read

CodeIgniter is one of the most popular PHP frameworks for building dynamic web applications. It’s known for its speed, small footprint, and excellent performance. In this guide, we’ll walk you through installing CodeIgniter on a local server in 2025. Let’s get started!

Prerequisites

Before we begin, ensure you have the following installed on your local machine:

  • PHP (version 8.0 or higher): CodeIgniter requires PHP to run.
  • Web Server (Apache or Nginx): A web server is needed to serve your CodeIgniter application.
  • Composer: PHP’s package manager, used for installing CodeIgniter.
  • Database Server (MySQL/MariaDB): While optional, a database server is necessary for dynamic data handling.

Step-by-Step Installation

Step 1: Set Up Your Local Server

  1. Install Apache or Nginx: If you haven’t already, install a web server. Tools like XAMPP, WAMP, MAMP, or LAMP can simplify this process.

  2. Ensure PHP is Installed: You can check your PHP version by running php -v in your terminal. Install or update PHP if required.

  3. Database Installation (Optional): If your application will use a database, ensure MySQL or MariaDB is installed and running.

Step 2: Download CodeIgniter

Using Composer

  1. Open your terminal or command prompt.

  2. Run the following command to create a new CodeIgniter project:

1
   composer create-project codeigniter4/appstarter example

Replace example with your preferred project name.

Without Composer

  1. Visit the official CodeIgniter website and download the latest version.

  2. Extract the downloaded zip file into your web server’s root directory, e.g., htdocs for XAMPP.

Step 3: Configure Your Application

  1. Set the Base URL:

Open the .env file in your project’s root directory and set the app.baseURL.

1
   app.baseURL = 'http://localhost/example/'

Adjust it based on your project folder name.

  1. Database Configuration:

If you’re using a database, open the app/Config/Database.php file and configure the connection settings.

  1. Enable Permissions:

Ensure the writable directory and its contents are writable by the webserver.

Step 4: Run Your CodeIgniter Application

  1. Open your web browser and navigate to:
1
   http://localhost/example/

You should see the CodeIgniter welcome page if everything is set up correctly.
