Since I built a PHP app that runs on Linux Windows and MacOS I just discovered that using gethostname() behaves differently on different OSes. Linux will return "hostname" while MacOS 10.15 will return "hostname.local"  . Have yet to determine how Windows behaves but the difference is worth noting. Only a few days ago I was wanting to get the LAN extension in Linux and was never able to. I was oly hable to get "hostname".  In MacOS it is just there. with "hostname.local"

To the prev. note: **NEVER USE***
#`sudo hostname servername`

Some *nix systems will then force to set the 'servername' as new hostname!

On Linux, use the command `hostname` to view your host name, or `sudo hostname servername` to set it
