Running yii application

hello, whilst trying to run a yii application using

"php -S 192.168.0.20:3310 --docroot=“frontend/web/”

i get

“PHP 8.2.1 Development Server (http://192.168.0.20:3310) started”

When trying to access the site in a browser (safari or any other) I get a blank page

My terminal reads

192.168.0.20:52312 Closing
192.168.0.20:52313 Accepted
192.168.0.20:52313 [200]: GET /favicon.ico
192.168.0.20:52313 Closing

Any assistance would be appreciated

FYI 192.168.0.20 in a browser goes direct to my localhost htdocs directory (which is not where my yii application is stored)

Anything in the logs?
