PHP formhash具体怎么做？
我在做一个购物网站遇到个问题。

比如某商品的库存只有1件。
如果这个时候有两个会员同时拍下来的话，就会变成两个订单，这个问题就很严重了，然商家库存只有一件，被拍了两件，

网上搜了下相关资料，发现formhash这个可以解决，但具体不知道怎么写，

谁能用PHP做一个简单的案例吗？
------解决思路----------------------
formhash >> form hash >> 哈希表
想象不出来这个玩意怎么能解决竞争
------解决思路----------------------
formhash貌似是用来防止刷帖机器的
有人下了订单直接数量-1呗，到时间还不付款再返还
