It's a change in the way PHP is set up; In PHP 3 (and possibly early
versions of 4?), "register_globals" was set to "on", which meant that you
didn't have to specify any variables before hand - they were created when
you asked for them.
Most PHP installations now have "register_globals" set to Off, and scripts
like the one you posted will be in trouble unless they're modified like
you've done above. That kind of script is understandable if written before
2002, but really is incredibly bad practice created done afterwards.
