PHP function executed and displayed as instant answer?

I just searched for the query "strtoupper with numbers" and received the response as seen in the attached image. I couldn't find anything pertaining to this result in the Help pages, although I didn't spend an inordinate amount of time looking.

I also tested strtolower, ucfirst, and ucwords, and only the last one failed to return a response as an instant answer as though properly executed through PHP.

Is this expected behavior?
