[PHP] using a regular expression to trim whitespace

[..s.c.o.t.t..]

there's a much easier way to get rid of whitespace
and linebreaks at the end of a variable than using a
looped ereg_replace (as i previously suggested)

1) use trim()
2) use preg_replace('/\s*$/', '', $input)

both will cremate spaces and linebreaks
