Setting REMOTE_USER for apache logs using php

Question

In mod_perl i can do something like:

$r->user("username");

And then the username will show up in the username section in the logs.

Is there a way to do this in php? without having to modify apache?

Edit: So far i've tried both:

$_SERVER['REMOTE_USER'] = "username";
$_SERVER['PHP_AUTH_USER'] = "username";
apache_setenv('REMOTE_USER', "username")

with no luck

Edit2: Apache logs are in the format of:

ipAddress REMOTE_USER IDENT datetime... etc

I'm trying to set REMOTE_USER without using apache's mod_auth, but php code.

Have you done a phpinfo() as an authenticated user? Somewhere in the resulting data, you should find your username... — Charles

my authenticated user is coming in programmaticly, not from apache. I know how to get the user from apache, i don't know how to tell apache what the user is. — Gavin Mogan

I'm confused. Are you or are you not trying to determine the username of the HTTP-authenticated user? If the user isn't HTTP-authenticated, then the things you're trying to do won't work. Can you edit your question to explain the nature of the authentication in more detail? — Charles

I'm trying to set it to save it to the apache logs. All of the things i've listed thus far is setting, not getting. Updated question. — Gavin Mogan

This looks like a likely option: apache_setenv()

Very cool, I did not know about that one, but unfortunately it did not work.

The trick is to use apache_setenv() along with changing your log_format to include %{REMOTE_USER}e

So you're basically passing the remote user as an environment variable, and grabbing that value in the log_format. As far as I know there's no way to override the 'original' variable.

I imagine you could simply override/provide the variable by setting the required super-global as you would any other variable. However that being said, a quick peak at the PHP docs and the variable you speak of isn't listed:

Sorry, see my update. I've already tried the two most obvious (to me) $_SERVER items.
