a simple getenv question....

Hi... A simple question... In the following code: <? $ip = getenv("REMOTE_ADDR"); echo " ip = ".$ip; echo " ip = " . getenv("REMOTE_ADDR"); echo " ip = " . getenv('REMOTE_ADDR'); echo " ip = ". $REMOTE_ADDR; <------ ?> I can only seem to get the last line to display the correct value. It's as if I can't seem to get/return any of the SERVER environment variables using the getenv() function.... I'm using Apache 2.0.40, PHP 4.2.2 on Linux RedHat 8.0. I've checked through the PHP.INI file, but couldn't seem to find why this might be occuring. Any help/assistance would be appreciated..... thanks bruce bedouglas@earthlink.net
