Here are two ways to test your webpages on simple servers. Open a terminal window in the folder you want to share on the LAN:
# python -m SimpleHTTPServer 8000
If you have PHP installed on the system, here’s another method:
# php -S localhost:8000
You can also run your php files, and read the error messages if there should be any errors in your code.
But beware … these simple servers are only meant for development. The methods are not secure at all. So use them wisely.
In both cases – can open your favorite browser in http://localhost:8000.
