$REMOTE_USER not working.

[Anon]

I am trying to get the Remote user name that shows up in PHPinfo();
This is what I use
if (!$s_user=$REMOTE_USER)$s_user="error";
it always shows up as error.
any ideas?

if ($s_user != $REMOTE_USER)$s_user="error";

If this is being done in a function make sure that you have specified that $REMOTE_USER is a global variable

ie
function blah {
global $REMOTE_USER

print $REMOTE_USER;

}

if (!$s_user = $REMOTE_USER) $s_user="error";

is a correct statement. It assignes $s_user the value $REMOTE_USER. If $REMOTE_USER is null then statement is false. It's a C thing and sometimes useful and at other times really confusing when you don't mean to do that.

That is what I meant to do sorry I worked in c or a long time

Thanks it was a scoping problem.
