How to Set Up a New Project in Codeigniter Step-by-step?

Setting up a new project in CodeIgniter can seem daunting if you’re new to the framework. However, with this step-by-step guide, you’ll find that it’s quite straightforward. Whether you’re developing a small application or a large web project, CodeIgniter offers a solid foundation for PHP development.

Step 1: Download CodeIgniter

First, download the latest version of CodeIgniter from the official website. Ensure that you have the right version for your PHP environment. After downloading, extract the files into your development directory.

Step 2: Configure the Base URL

Navigate to the application/config/config.php file and set your base URL:

1

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

Make sure this URL matches the directory where you’ve set up CodeIgniter on your local server.

Step 3: Set Up Database Configuration

If your project requires a database, you need to configure it in the application/config/database.php file. Fill in your database credentials as shown below:

$db['default'] = array(
    'dsn'   => '',
    'hostname' => 'localhost',
    'username' => 'your_username',
    'password' => 'your_password',
    'database' => 'your_database',
    'dbdriver' => 'mysqli',
    'dbprefix' => '',
    'pconnect' => FALSE,
    'db_debug' => (ENVIRONMENT !== 'production'),
    'cache_on' => FALSE,
    'cachedir' => '',
    'char_set' => 'utf8',
    'dbcollat' => 'utf8_general_ci',
    'swap_pre' => '',
    'encrypt' => FALSE,
    'compress' => FALSE,
    'stricton' => FALSE,
    'failover' => array(),
    'save_queries' => TRUE
);

Step 4: Configure Autoload Settings

To streamline your project, autoload commonly used resources like libraries, helpers, and more using the application/config/autoload.php file. Example:

1

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

Step 5: Set Up Default Controller

Define your default controller in application/config/routes.php to dictate which controller should be loaded by default.

1

$route['default_controller'] = 'welcome'; // Assuming 'Welcome' is your default controller

Step 6: Enable URL Rewriting (Optional)

To remove index.php from your URLs, create a .htaccess file in your root directory with the following configuration:

RewriteEngine On
RewriteBase /your_project_name/
RewriteCond %{REQUEST_FILENAME} !-f
