php生成唯一的订单函数分享_PHP
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
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。
