Radar is a PSR-7 compliant Action-Domain-Responder (ADR) system. While it may look like a micro-framework, it is more like a wrapper around the real core of your application domain.

You will need Composer to install Radar.

Pick a project name, and use Composer to create it with Radar; here we create one called example-project:

composer create-project -s dev elevenone/radar.zombie example-project

Confirm the installation by changing into the project directory and starting the built-in PHP web server:

cd example-project
php -S localhost:8080 -t web/

You can then browse to http://localhost:8080/ and see JSON output:

{"phrase":"Hello world"}

You can also browse to http://localhost:8080/your-name and see modified JSON output:

{"phrase":"Hello your-name"}
