How to Set Up a New Project in CodeIgniter: Step-by-Step Guide

If you're a developer looking to start a project using CodeIgniter, a powerful PHP framework, you've come to the right place.

This step-by-step guide will walk you through setting up a new project in CodeIgniter.

Step 1: Download CodeIgniter

First, download the latest version of CodeIgniter from the official CodeIgniter website. Once downloaded, extract the file contents to your desired project directory on your server or local development environment.

Step 2: Configure Your Base URL

Navigate to the application/config/config.php file in your CodeIgniter project directory. Set your base URL by editing the following line:

$config['base_url'] = 'http://yourdomain.com/';

Ensure that the URL is correct according to your environment, whether it's local or on a server.

Step 3: Set Up Your Database Configuration

Edit the application/config/database.php file to match your database settings. Fill in the hostname, username, password, and database name fields:

$db['default'] = array(
    'dsn'   => '',
    'hostname' => 'localhost',
    'username' => 'your_db_username',
    'password' => 'your_db_password',
    'database' => 'your_db_name',
    'dbdriver' => 'mysqli',
);

Step 4: Enable URL Rewriting to Remove "index.php"

Remove "index.php" from your URLs for cleaner links. Create a .htaccess file in the root of your project directory and add the following content:

RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

Step 5: Set Up Routing

Manage user-friendly URLs by configuring routing in the application/config/routes.php file. Ensure the default controller is set correctly:

$route['default_controller'] = 'welcome';

Modify it as per your controller names.

Step 6: Utilize CodeIgniter SEO Plugins
