最近我正在使用PHP和PHPMyAdmin开发充值系统。
注意-在充值系统中，所有充值并非始终都成功。因此，我添加了代码以检查充值API提供程序的充值状态。 （按照充值API规则，在充值任何数字后，它会显示待处理的1-2分钟，然后变为成功或失败）。如果充值失败，则应使用带有此代码的cron job将金额退还给用户。在这里，我们有3种类型的用户-管理员，分销商，代理商（所有用户均可通过充值获得佣金）
状态cron工作代码-

我遇到的最大问题是同时进行多个用户余额数据库更新。例如，用户为手机号码充值，与此同时，用户收到因cron作业检查码充值失败而产生的退款。在这种情况下，我的代码无法正常工作。因为两次更新之间（充值金额扣除和增加退款金额）之间，数据库中未计算每个更新查询中的一个。
示例-用户余额100美元
充电-10 $
并退款-20 $
因此，最终金额应为110 $，但未计算充值金额。因此，余额显示为120 $，有时不计算收到的退款金额。如果两个事务都在一个非常独特的情况下同时完成，但是经过长时间的调试和错误检查之后，我发现问题出在我的代码上。因此，请帮助我修复它。我想一个一个地更新数量数据库。
