请教 Mysql事务回滚怎么写？
就是俺现在碰到一个问题：论坛扣币项目中，用户支付论坛币的时候如果突然断网、电脑死机、停电、等其它自然灾害时，导致本次交易没有成功（即用户的币已经扣掉了，但是服务器数据库中没有消费记录等其它情况），这种情况是用Mysql事务回滚处理吗？代码怎么写？还有别的办法吗？

————期待前辈高手详解！

------解决方案--------------------
没有commit是不会生效的, 回滚是取消的意思, 不是提交的意思.

这个也没什么好讲的，网上大把的教程，找了一段给你自测，尝试着把sql写错然后看看效果

PHP code

mysql_query("BEGIN"); //或者mysql_query("START TRANSACTION");$sql = "INSERT INTO ...";$sql2 = "INSERT INTO ...";$res = mysql_query($sql);$res1 = mysql_query($sql2); if($res && $res1){    mysql_query("COMMIT");    echo '提交成功。';}else{    mysql_query("ROLLBACK");    echo '数据回滚。';}mysql_query("END");<div class="clear">
                 
              
              
        
            </div>

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
