[PHP]讨论下支付宝和微信群红包分配金额的实现思路

想必都玩过支付宝和微信的红包吧,发红包有个群红包,填写好总金额和个数。

想问下,这个每份的金额是点击确定的时候就确定好了还是用户点击领取的时候分配的?

用PHP来如何随机分配的金额以及总数一致呢?

用PHP来如何随机分配的金额以及总数一致呢?

1、每个人都要能够领取到红包;
2、每个人领取到的红包金额总和=总金额;
3、每个人领取到的红包金额不等,但也不能差的太离谱,不然就没趣味;

<code>header("Content-Type: text/html;charset=utf-8");//输出不乱码,你懂的
$total=10;//红包总额
$num=8;// 分成8个红包,支持8人随机领取
$min=0.01;//每个人最少能收到0.01元

for ($i=1;$i';
}
echo '第'.$num.'个红包:'.$total.' 元,余额:0 元';
</code>
