  According to the php 2.0 doc's (I am using 3.0) PHP isn't
supposed to allow the overwriting of environment variables
by adding "?".  I have the
following file "test.php3" in my doc root:

<?echo "remote_host=$REMOTE_HOST";?>

And then I pointed netscape at:

And it returned:

Am I missing something?

On a similar topic, I need to get at the REMOTE_USER environment
variable without the user being able to change this.  I use
the .htaccess method of authentication, but I need to know
the username of the remote user.  In my old perl scripts I
just checked REMOTE_USER, but PHP seems to allow the user
to overwrite this.
