Setting up a new project in CodeIgniter can seem daunting at first, but breaking it down into manageable steps can make the process straightforward. CodeIgniter, a powerful PHP framework, is designed for developers who need a simple and elegant toolkit to create full-featured web applications. Let’s dive into how you can set up your project efficiently.

Step 1: Download CodeIgniter

1. Visit the official CodeIgniter website.
2. Download the latest release of CodeIgniter.
3. Extract the downloaded file to your local server directory.

Step 2: Set Up Your Environment

Navigate to your server’s document root (e.g., htdocs for XAMPP, www for WAMP) and copy the extracted CodeIgniter folder there. You can rename it to your project name for easier access.

Step 3: Configure the Base URL

1. Open the application/config/config.php file.
2. Set the base URL of your project:

1

   $config['base_url'] = 'http://localhost/your_project_name/';

1. Ensure that the base URL is properly set to match your project’s directory path.

For additional security and protocol settings, you might want to redirect HTTP traffic to HTTPS. Follow this guide on how to redirect protocol.

Step 4: Set Up the Database

1. Open application/config/database.php.
2. Input your database settings including hostname, username, password, and database name:

       'password' => 'your_password',
       'database' => 'your_database_name',
       'dbdriver' => 'mysqli',
   );

Step 5: Configure Autoload Settings

1. Open application/config/autoload.php.
2. Autoload the necessary libraries and helpers:

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

Navigate to application/config/routes.php to set up your default controller and any additional routes your application may need.

$route['default_controller'] = 'welcome';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;
