PHP對毫秒級字符串轉換

private function _get_microtime_format($time)
    {
        if(strstr($time,'.'))
        {
            sprintf("%01.3f",$time);
            list($usec,$sec) = explode(".", $time);
            $sec = str_pad($sec,3,"0",STR_PAD_RIGHT);
        }else
        {
            $usec = $time;
            $sec = "000";
        }
        $date = date("Y-m-d H:i:s.x", $usec);
        return str_replace("x", $sec, $date);
    }
