点击登录就会出现apache应用程序错误。
之后随便写一个页面php连接数据库就出现这个错误。
回复讨论(解决方案)
真蛋疼,以前装软件要按顺序,现在写环境变量也要按顺序,擦了,我去。
问题解决方案:
php连接数据库导致apache应用程序出错
随便写句吧,分给你们。
没有遇到过。。
为什么要修改环境变量PATH呢?
apache、mysql、php 都可以绿色安装,并且运行时并不依赖注册表
你可以卸载一下再安装就行了

下次装系统的时候去试一试。
不要下次,这次就把你的环境拷贝出来,放到U盘中运行一下
当然要把配置文件中的盘符都删掉的

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.

PHP sessions have a significant impact on application performance. Optimization methods include: 1. Use a database to store session data to improve response speed; 2. Reduce the use of session data and only store necessary information; 3. Use a non-blocking session processor to improve concurrency capabilities; 4. Adjust the session expiration time to balance user experience and server burden; 5. Use persistent sessions to reduce the number of data read and write times.

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.
