getenv() is actually the more portable way to do this since there is no
guarantee that $_SERVER is enabled.

It won't be. getenv() first checks the server environment and if it
doesn't find the value there it checks the underlying real environment.

If getenv() doesn't find it, $_SERVER definitely won't either. This is
a var set by the web server, so if it is missing, look at the web server
for the problem.
