Environment Variables

Hello. I have run into a weird problem with php. I have a very short php script that will print out a particular environment variable. Here is the contents of an index.php file: <html><head><title>Test</title></head> <body bgcolor="#FFFFFF"> <b> LOOK -- <? print($MY_VAR); ?></b> </body></html> Now, when I go to http://server/index.php, it prints out my variable as I want. LOOK -- MY Test Variable But, when I just go to http://server/ (and I have index.php as a directory index in the apache server config file) the variable isn't set and all I get is: LOOK -- Anybody have any ideas what may be causing this behavior? Thanks in advance. -- Bob Morse Senior Systems Programmer Brown University
