Not that's guaranteed to be provided by every host. $_SERVER['PHP_SELF'] (the
real name - it's a member of the $_SERVER array) is good because it's always the
name of the page being displayed. That has to be gotten from the server.

But I wouldn't worry about it. It's available in Apache and IIS. Those account
for > 99% of the servers on the web.
