I have a regular expression check as: preg_match("/$xyz/", $data, $matches); And, as you know $xyz means "string starts with xyz". But somehow PHP 5 is interpreting this as variable xyz, and gives the notice below. You can ignore the message, but now it matches everything that has xyz, i.e. aaxyzbbEither use single quotes: preg_match('/$xyz/', $data, $matches); or escape the $-sign: preg_match("/\$xyz/", $data, $matches); -- Jasper Bryant-Greene Freelance web developer http://jasper.bryant-greene.name/ If you find my advice useful, please consider donating to a poor student!
