PHP 出现 PHP has encountered an Access Violation at 02C9A0F0,该怎么解决
PHP 出现 PHP has encountered an Access Violation at 02C9A0F0
现在有个网站提交表单后出现这个问题
我的环境是windows+php php版本是:PHP Version 5.2.5
提交表单后程序做以下工作,1,验证表单信息是否规范,2,soap调用外部程序验证客户保险信息
这个问题不经常出现,出现的时候反复刷新几次就可以了。但这究竟是什么问题呢,在网站找的说什么PHP eaccelerator 问题,我PHP.ini就没有这个
还有说是SESSION路径问题,这个不可能啊,我后台登陆都没有问题,而且提交表单用不上SESSION
还有说是c:/winnt/temp 权限问题,我把这个环境变量因为安全问题,放在其实文件夹里了,而且给访问都权限了。
还有说内存不足,这个不太可能吧,我服务器是8G内存而且是新站没有多少人访问啊
还有说应用池中设定了限制 这个我把限制都去掉了。
很郁闷,请高手解决,粘贴复制的就要了,谢谢

是否以前裝過不同版本的php?

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.

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.
