usar el servidor de php
Run Your Application With PHP’s Webserver:
php -S localhost:8080
This will make your application available at http://localhost:8080 (if you’re already using port 8080 on your machine, you’ll get a warning. Just pick a different port number, PHP doesn’t care what you bind it to).
Note you’ll get an error message about “Page Not Found” at this URL - but it’s an error message from Slim, so this is expected. Try http://localhost:8080/hello/joebloggs instead :)
