You should be aware that it is possible that a UA doesn't sent a
referrer header.

The double )) is wrong; just use a single ). You may consider to use
only simple expressions for an if expression, e.g.:
$cameFromExpectedPage = substr($referrer, -13) === 'formcheck.php';
if ($cameFromExpectedPage) {
echo 'Something showed up';
}
