我正在尝试在 php 和 mysql 中做一个小应用程序。

问题： 数据库损坏，我随机丢失数据。总是丢失的数据是事务的一部分，绝不是完整的事务，只是事务的一部分。

关于应用程序的信息： Wampserver 用于 Windows 7 机器上的基本设置。该机器是个人桌面。该应用程序不会在线托管，它将始终在本地服务器上运行。

这是 mysql 日志的一部分

这是我正在使用的代码 - PHP CODE

请注意 ：

  • 我不确定这是我的代码还是其他问题。
  • 代码不好，这是我第一次写超过 2 行的 PHP。
  • 需要检查的代码是从第11行到第198行
  • 丢失数据的 mysql 查询位于第 176 行

任何帮助表示赞赏。
