研究discuz发现:其中它有一个C类
即然是C类,那么肯定要事先声明创建的,而php的创建类的方式,我学习php只有一个办法,那就是 class C{ };
可是我搜了一下这个字样class C{ 根本就没有,查了下百度,有人说这个是创建C类的代码:
C::creatapp();class core{ private static $_tables; private static $_imports; private static $_app; private static $_memory; public static function app() { return self::$_app; } public static function creatapp() { if(!is_object(self::$_app)) { self::$_app = discuz_application::instance(); } return self::$_app; }
但,这里面哪有class C{字样呢,难道我学的php创建类的知识不对吗,我晕,!
回复讨论(解决方案)
你没看到 class C extends core {} 这样的代码吗?
/source/class/class_core.php
文件最下面不是有句这个么...
class C extends core {}

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.
