Php sms信用扣减并发问题

我目前正在为最终用户编写一个sms系统。然而，当我对函数进行测试时，我遇到了sms信用扣减错误

此功能中有三个表，即公司、用户和交易

我对这个函数做了很多测试。只是不能正确获得信用扣减

例如，每个表中有1000个学分

初始值

company.sms_bal=1000

user.user\u credit\u bal=1000

transaction.transaction\u余额=1000

测试#1 每张表扣1分。它能正确地推断

company.sms_bal=999

user.user\u credit\u bal=999

transaction.transaction\u余额=999

测试#2 每张表扣2分。它推断错误

company.sms_bal=997

user.user\u credit\u bal=997

transaction.transaction_balance=998假设为997

p/S它并不总是错误地扣除，只是有时。请给我忠告。但是，如果你不确定我的问题，请告诉我我愿意帮助你

下面是供您参考的函数
