把每次都要执行的部分抽出来
php中,共有3个函数,其中绝大分数是相同的。如何能更科学的变成一个函数,从而搞效率。
方法一:将此3个函数变成一个,怎么实现呢?
方法二:奖此3个函数的执行体,就是输出的部分公共部分,单独做个函数。如何实现呢?????

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.
