@AasSuhendar What do you mean by not working? What happened? Any error messages?

I run a comand line bin/server.sh to run php built-in server, and then i write url 127.0.0.1:8000, but the web page not appear. The error message in my browser "This Web Page is not avalilable".
a comand line bin/server.sh is equals php -S localhost:8000 or 127.0.0.1:8000 it is right? Because i had seen in bin\server.sh it same way. But, why the web page not appear when i run with your comand line. I'm sorry, I still beginner master. Thanks

@AasSuhendar Did you install CodeIgniter like the following?

$ composer create-project kenjis/codeigniter-composer-installer codeigniter

bin/server.sh is equals to php -S 127.0.0.1:8000 -t public/ bin/router.php.

Yes, follow that way.
I have tried again to install new project but still same condition.
