CodeIgniter, known for its simplicity and speed, is an excellent choice for developers looking to build dynamic websites. Follow this step-by-step guide to set up your new CodeIgniter project.

Step 1: Downloading CodeIgniter

First, download the latest version of CodeIgniter from the official CodeIgniter website. Extract the downloaded package into your web server’s root directory or your local development environment.

Step 2: Configuring Your Project

Once your files are extracted, rename the folder to reflect your project name. Navigate to the application/config directory to adjust the configuration settings. Begin by setting the base URL in the config.php file:

    'database' => 'your_database',
    'dbdriver' => 'mysqli',
    ...
