PHP生成唯一订单号的方法汇总,php订单号汇总
第一种
复制代码 代码如下:
return date('Ymd') . str_pad(mt_rand(1, 99999), 5, '0', STR_PAD_LEFT);
第二种
复制代码 代码如下:
return date('Ymd').substr(implode(NULL, array_map('ord', str_split(substr(uniqid(), 7, 13), 1))), 0, 8);
第三种
//生成24位唯一订单号码,格式:YYYY-MMDD-HHII-SS-NNNN,NNNN-CC,其中:YYYY=年份,MM=月份,DD=日期,HH=24格式小时,II=分,SS=秒,NNNNNNNN=随机数,CC=检查码 @date_default_timezone_set("PRC"); while(true){ //订购日期 $order_date = date('Y-m-d'); //订单号码主体(YYYYMMDDHHIISSNNNNNNNN) $order_id_main = date('YmdHis') . rand(10000000,99999999); //订单号码主体长度 $order_id_len = strlen($order_id_main); $order_id_sum = 0; for($i=0; $i<$order_id_len; $i++){ $order_id_sum += (int)(substr($order_id_main,$i,1)); } //唯一订单号码(YYYYMMDDHHIISSNNNNNNNNCC) $order_id = $order_id_main . str_pad((100 - $order_id_sum % 100) % 100,2,'0',STR_PAD_LEFT);
第四种:
在网上找了一番,发现这位同学的想法挺不错的,redtamo,具体的请稳步过去看看,我作简要概述,该方法用上了英文字母、年月日、Unix 时间戳和微秒数、随机数,重复的可能性大大降低,还是很不错的。使用字母很有代表性,一个字母对应一个年份,总共16位,不多也不少,呵呵。
<?php $yCode = array('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J'); $orderSn = $yCode[intval(date('Y')) - 2011] . strtoupper(dechex(date('m'))) . date('d') . substr(time(), -5) . substr(microtime(), 2, 5) . sprintf('%02d', rand(0, 99)); ?>
生成效果:

唉,不过很可惜,最后项目并没有使用这种方法,说是没必要搞这么复杂, - -!
