public static function sqlFunctionRegexp($pattern, $subject) {
  // preg_quote() cannot be used here, since $pattern may contain reserved
  // regular expression characters already (such as ^, $, etc). Therefore,
  // use a rare character as PCRE delimiter.
  $pattern = '#' . addcslashes($pattern, '#') . '#i';
  return preg_match($pattern, $subject);
