    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"

    Regarding Linux vs. macOS, that is not a difference in OS or PHP. macOS sets the hostname to <shortname>.local. Open a terminal window and run `hostname` to check. The local hostname can be set on macOS under the Sharing Preferences (or Settings if Ventura 13 or newer).

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

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

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