How to document parameters received by function "func_get_args"?

How can I be documenting parameters that are received through the func_get_args function?

The reason is to be able to pass several parameters to the function for the same purpose!

/**
 * Gets a smart text filtered and formatted of according with the property name provided
 *
 * @param string $code The property name to be called
 *
 * @return string Returns the content of property in '$code' with formatting filter as a string
 * @see   Skreth\Code\Text::getTexts()
 * @since 0.2
 */
public static function code($code)
{
    if (!is_string($code)) throw new InvalidArgumentException("Smart text is not a string");

    return StringFilter::formatting(self::getTexts($code));
}

As well, it may be possible to pass several $code :

public static function code()
{
    $code = func_num_args();
    $result = [];

    foreach ($code as $value) {
        if (!is_string($value)) throw new InvalidArgumentException("Smart text is not a string");

        $result[] =  StringFilter::formatting(self::getTexts($value));
    }

    // OU, TALVEZ (Acredito que foreach seja mais perfomático, estou certo?)...
    $result = array_map(function ($value) {
        if (!is_string($value)) throw new InvalidArgumentException("Smart text is not a string");

        return StringFilter::formatting(self::getTexts($value));
    }, $code);

    return implode(' ', $result);
}

I accept good programming practice tips too: D
