PHP实在让人头痛,看不懂啊,被老大叼得不行了,大家帮我看段团购网的代码是什么
PHP实在让人头痛,,看不懂啊,被老大叼得不行了
大家帮我看看这代码是什么
,
这些CMS实在是服了,,一个文件就写那么点代码,,有的更少,一个文件就设置一个变量
首页INDEX全都是PHP程序,一个HTML字符都不见,,,HTML表单提交到的是本页面,也不知道它为什么能处理这么多事,也不见它连接到哪里,,,
什么页面都是 index.php?H()&*T&GO*UGHPO*Y()G 要么就是?H(*Y(H*&YIJOU**((*((*&896897
什么页面的地址都是这样,气死了,根本不知道它这个页面的模板在哪里,,找啊找,找半天,
找模板就算了,
那些页面连接到哪里处理,调用哪里的程序段实在让我头大,很想撞豆腐,,很想撞个几百吨的,,
,
下面的代码是一行搜索的代码,,有下拉框的值,那个值去哪里取的?
头两句怎么解释?
select有点击执行onclick or onchange的动作,它这里没有,怎么搞的?
这应该是天天团购的,,我想在产品管理页面里加按 分类 显示,,有没有人支招?先感谢,,,

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.
