Code

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);
