Description:
------------
---
From manual page: https://php.net/function.gethostname
---
The documentation does not say anything about whether the return value is a fully-qualified domain name or not; sometimes it is, sometimes it is not.

It should mention that it could return either and explain what causes it to do one or the other.

PHP is merely reporting what your system says. There's no logic about making it fully-qualified or not.

I suggest adding:

The value is the output of the system hostname command. Depending on system configuration, this will be either the fully-qualified domain name or just the local part of the name.

I wouldn't even mention fully-qualified - just say that it's from the system, consult your system's documentation, the usual that we do for functions like this.

OK, how about:

The value is the output of the system hostname command, which will depend on system configuration. Consult your system documentation.
