@davy_yg I know a while back you had questions on php artisan serve .
However you said:
If you run that and you debug the program once again and press refresh browser. Will the updated code also refreshed without having to re-run php artisan serve?
Give it a try, change some code and do a browser refresh. However, I usually have to also clear browser cache then refresh.
But feel free to experiment with this stuff like we do. Go ahead and give it a try.
Just remember, it's best to setup a regular development environment and not use php artisan.
One I like better for Windows than xampp is bitnami: https://bitnami.com/stack/wamp/installer
