PHP除了在web端大展拳脚外,在后台的进阶工具有什么呢?
大家都推荐一下,说下优势或者差别?
我目前了解到的就是swoole和workerman、gearman。
swoole是拓展形式的异步工具,但最新版本好像取消了分布式方向。
workerman和swoole比起来就更方便,因为不需要拓展,俩种工具的对比不详。
gearman是分布式框架,也是PHP后端分布式利器。
工具最少得稳定、社区活跃吧?

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.
