apache_getenv(key) does not work on an php cgi installation, in this case rather use $_SERVER["REDIRECT_key"]

This manual page is unclear as to whether it will fetch Apache configuration environment variables set by "SetEnv" (including "SetEnvIf[NoCase]" or "BrowserMatch" e.g.) as the only example given is with a pre-defined CGI interface variable (which is also available via the $_SERVER[] array).  If custom Apache runtime configuration variables are indeed fetchable via this interface, let's say so or give an example of such.
