php支持windows的basename函数

It's a shame, that for a 20 years of development we don't have mb_basename() yet!

// works both in windows and unix
function mb_basename($path) {
    if (preg_match('@^.*[\\\\/]([^\\\\/]+)$@s', $path, $matches)) {
        return $matches[1];
    } else if (preg_match('@^([^\\\\/]+)$@s', $path, $matches)) {
        return $matches[1];
    }
    return '';
}
