Server Variables Limited?

I've been searching, but I can't seem to find a server variable that outputs the current website.

There's: PHP_SELF, REQUEST_URI, SCRIPT_URI, and others, but they seem to give an output like:

/var/www/html/contactus.php

I just want: "contactus.php"

Is there such a variable?

$_SERVER['SCRIPT_NAME'];

I've tried that one. I get the filename, plus the path:

$_SERVER[SCRIPT_NAME] = /sysadmin/testing_pages/server_variables.php

Am I missing something?

Sorry. 😃 What about this?

substr( strrchr($_SERVER['SCRIPT_NAME'], '/'), 1 );

Or [man]basename[/man].
