as this example you can change ip and port this works with me
php artisan serve --host=0.0.0.0 --port=8000
you can also add host as well with same command like :
php artisan serve --host=172.10.29.100 --port=8080
You can use
php artisan serve --port 80
Works on Windows platform
Andreas' answer above was helpful in solving my problem of how to test artisan on port 80. Port 80 can be specified like the other port numbers, but regular users do not have permissions to run anything on that port.
Drop a little common sense on there and you end up with this for Linux:
sudo php artisan serve --port=80
This will allow you to test on localhost without specifying the port in your browser. You can also use this to set up a temporary demo, as I have done.
Keep in mind, however, that PHP's built in server is not designed for production. Use nginx/Apache for production.
You can use many ports together for each project,
php artisan serve --port=8000
php artisan serve --port=8001
php artisan serve --port=8002
php artisan serve --port=8003
One can specify the port with: php artisan serve --port=8080
.
sudo /Applications/XAMPP/xamppfiles/bin/apachectl start
This fixed my issue AFTER ensuring my ports were all uniquely sorted out.
