I have put my laravel project in htdocs file and when I open http://192.168.64.2/laravelproject/public/ this error is showing up.

No one but you can open that url you linked, because it is local your computer.

Is it also possible to run laravel (folder is saved on my desktop) via terminal php artisan serve and run xampp phpadmin. Or do I have to place that folder in htdocs?
