是否有可用于PHP的文件描述脚本的文件扩展名？

function ext_description($extension) {
    static extensions = array(
        \'png\' => \'Portable Network Graphic\',
        \'doc\' => \'Microsoft Office Word Document\'
    );
    $extension = strtolower($extension);
    return isset($extensions[$extension])
        ? $extensions[$extension]
        : sprintf(\'Unknown File (%s)\', $extension)
        ;
}

function ext_description($extension) {
    switch ($extension) {
    case \"png\":
        return \"Portable Network Graphic\";
    case \"doc\":
        return \"Microsoft Office Word Document\";
    default:
        return \"Unknow extention\";
}
