框架VS自已!!想问一下自已写程序运行效率是不是没有框架高?
框架VS自已!!想问一下自已写程序运行效率是不是没有框架高?
我看到好多人提到框架,为什么要用框架?就是为了开发速度快?
如果排除开发速度,协同原因,那自已写原生态代码运行效率上就没有框架的高吗?
困扰很久,不知是用框架还是不用框?观摩中国知名的CMS有那几个用ZD,YII,TP 等主流框架的,好象没有?
希望能解一个凝惑,(千万不要跟我说开发速度快协同好原因)

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.

The steps to build an efficient shopping cart system using sessions include: 1) Understand the definition and function of the session. The session is a server-side storage mechanism used to maintain user status across requests; 2) Implement basic session management, such as adding products to the shopping cart; 3) Expand to advanced usage, supporting product quantity management and deletion; 4) Optimize performance and security, by persisting session data and using secure session identifiers.
