关于生成订单号的解决方案

电子商务及类电子商务的系统越来越多,我相信订单号问题是这类系统中最常见不过的一个问题了,但今天还是想谈谈。

这几天由于工作需要接手了另外一同事前期开发的一个交易系统,原本使用的是uniqid()函数生成的。理论上也是不会出现重复,,但由于一些特殊的原因,不得不重新制作一款订单号的生成函数

复制代码 代码如下:


/**
     * 生成唯一的订单号 20110809111259232312
     * 2011-年日期
     * 08-月份
     * 09-日期
     * 11-小时
     * 12-分
     * 59-秒
     * 2323-微秒
     * 12-随机值
     * @return string
     */
    public function trade_no() {
        list($usec, $sec) = explode(" ", microtime());
        $usec = substr(str_replace('0.', '', $usec), 0 ,4);
        $str  = rand(10,99);
        return date("YmdHis").$usec.$str;
    }

以上就是本文的全部内容了,希望大家能够喜欢。
