Starting a new project in CodeIgniter, a powerful PHP framework, can be both exciting and daunting. To help you get started smoothly, this step-by-step guide will walk you through the process of setting up a new project in CodeIgniter.

Step 1: Download CodeIgniter

First, download the latest version of CodeIgniter from the official website. Extract the downloaded file to your desired project location on your server.

Step 2: Configure Base URL

Open application/config/config.php and set the base URL. This is essential for CodeIgniter to know the root URL of your application.

$config['base_url'] = 'http://your-domain.com/';

Step 3: Set Up Database Configuration

In the application/config/database.php file, configure your database settings.

$db['default'] = array(
    'dsn'    => '',
    'hostname' => 'localhost',
    'username' => 'your_username',
    'password' => 'your_password',
    'database' => 'your_database',
    'dbdriver' => 'mysqli',
    'dbprefix' => '',
    ...
);

Step 4: Configure Autoload

Adjust the autoload.php file in the application/config directory to autoload the libraries, helpers, and packages you will frequently use.

$autoload['libraries'] = array('database', 'session');
$autoload['helper'] = array('url', 'form');

Step 5: Remove index.php from URLs

To clean up your URLs by removing index.php, you can follow this guide on removing index.php.

Step 6: Secure Your Application

Ensure your site is secure by redirecting from HTTP to HTTPS. For details, see this article on HTTP to HTTPS redirection.

Step 7: Create Your First Controller

Create a new file named Welcome.php in the application/controllers directory with the following code:

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Welcome extends CI_Controller {
    public function index() {
        $this->load->view('welcome_message');
    }
}

Additional Features

By following these steps, you will have a functional CodeIgniter project up and running in no time. Happy coding!
