一个关于父类方法访问子类对象中的公有属性的问题
如图所示:
------解决思路----------------------
private $_name = '韩'; 是父类私有属性,所以子类不能修改其值。
showName是父类方法,所以把父类的$_name = '韩'; 输出。
把private 改为 protected 或 public就可以了。
------解决思路----------------------
你把 echo '
类:'.get_class($this).',方法:'.__METHOD__;
改成 echo '
类:'. __CLASS__ .',方法:'.__METHOD__;
就可以从结果中看出了
p1=10,_name=康
p1=10,_name=韩
类:Han,方法:Han::showName
虽然 Kong 了继承了 Han 的方法 showName (__METHOD__ 为 Han::showName)
但他依然工作在 Han 类中,那么 $this->_name 就是 Han::_name 并且永远都是
如果 Han::_name 不是私有的,那么 Kong::_name 将会覆盖 Han::_name
但并不是说 $this->_name 访问的是 Kong::_name,而实际上依然是 Han::_name,只不过两个的值相同而已

In PHP, you can use session_status() or session_id() to check whether the session has started. 1) Use the session_status() function. If PHP_SESSION_ACTIVE is returned, the session has been started. 2) Use the session_id() function, if a non-empty string is returned, the session has been started. Both methods can effectively check the session state, and choosing which method to use depends on the PHP version and personal preferences.

Managing concurrent session access in PHP can be done by the following methods: 1. Use the database to store session data, 2. Use Redis or Memcached, 3. Implement a session locking strategy. These methods help ensure data consistency and improve concurrency performance.

Load balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

Sessionhijacking refers to an attacker impersonating a user by obtaining the user's sessionID. Prevention methods include: 1) encrypting communication using HTTPS; 2) verifying the source of the sessionID; 3) using a secure sessionID generation algorithm; 4) regularly updating the sessionID.
