WAMP服务器上运行，提示 HTTP 500内部服务器错误。
请问一下，
原来在服务器上运行正常的CAKE网站，
原码下载以后。
在本地的WAMP服务器上运行，
提示 HTTP 500内部服务器错误。

这个怎么解决？
请详细一些。
谢谢

------解决思路----------------------
服务器的环境和原先的一致？具体可以查看服务器日志
------解决思路----------------------
php.ini 中
display_errors = On
这是排除的必要条件

访问网站，截个图贴出来
你是 widows 系统，同时按下 Alt + Prlsc 键，将活动窗口截图到裁剪版；打开画图，从裁剪版粘贴；做适当处理后，另存为 jpg 格式（CSDN不支持 bmp 图片上传）。无需其他软件支持
------解决思路----------------------
出现 500 错误时，通常是 php 程序出现了错误，打开错误显示功能一般都能看到错误信息
如果不是 php 成寻的问题，那就要看服务器日志了
来自网页的消息的弹窗是由 js 产生的，由于 php 程序出错，造成错误信息混杂在 js 代码中，从而导致 js 代码语法错

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.
