Let’s get started.
CodeIgniter 4 Installation
To create a CodeIgniter 4 setup run this given command into your shell or terminal. Please make sure composer should be installed.
composer create-project codeigniter4/appstarter codeigniter-4
Assuming you have successfully installed application into your local system.
Environment (.env) Setup
When we install CodeIgniter 4, we will have env file at root. To use the environment variables means using variables at global scope we need to do env to .env
Either we can do via renaming file as simple as that. Also we can do by terminal command.
Open project in terminal
cp env .env
Above command will create a copy of env file to .env file. Now we are ready to use environment variables.
Enable Development Mode
CodeIgniter starts up in production mode by default. You need to make it in development mode to see any error if you are working with application.
Open .env file from root.
# CI_ENVIRONMENT = production
// Do it to
CI_ENVIRONMENT = development
Now application is in development mode.

$curl = \Config\Services::curlrequest();
OR
$curl = service('curlrequest');
Create Controller (cURL PUT Request)
Back to project terminal and run this command to create a controller file.
php spark make:controller Data --suffix
Above command will create a file i.e DataController.php inside /app/Controllers folder.
Open DataController.php and write this code into it.
<?php namespace App\Controllers; use App\Controllers\BaseController; class DataController extends BaseController { public function index() { $curl = service('curlrequest'); $posts_data = $curl->request("PUT", "https://api.onlinewebtutorblog.com/employees/1", [ "headers" => [ "Accept" => "application/json" ], "form_params" => [ "username" => "sanjay_owt", "name" => "Sanjay Kumar", "email" => "sanjay_sample@example.net" ] ]); echo "<pre>"; print_r($posts_data->getBody()); } }
Create Route
Open Routes.php file from /app/Config folder. Add this route into it.
//... $routes->get("employees", "DataController::index"); //...
Application Testing
Open project terminal and start development server via command:
php spark serve
