800apcnbspsize

APC配置问题
我的php.ini对apc的配置有如下一段：
[apc]
apc.cache_by_default =On
apc.enable_cli =Off
apc.enabled =On
apc.file_update_protection =2
apc.filters =""
apc.gc_ttl =3600
apc.max_file_size =1M
apc.num_files_hint =1000
apc.optimization =On
apc.shm_segments =1
apc.shm_size =800
apc.slam_defense =Off
apc.stat =On
apc.ttl =0
apc.user_entries_hint =100
apc.user_ttl =0

对apc.shm_size的解释是：
每个共享内存块的大小(以MB为单位，建议值为128~256)。有些系统(包括大多数BSD变种)默认的共享内存块大小非常少。

这个值在设置为800时，加载数据会造成内存溢出，但是改小了（如300）就正常了。请问我从哪里可以知道我的系统允许的apc.shm_size的最大值？

------解决方案--------------------
apc.shm_size (以MB为单位，建议值为128~256)。

你的内存多大？搞800那么大。真牛人

How can you check if a PHP session has already started?Apr 30, 2025 am 12:20 AM

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.

Explain how load balancing affects session management and how to address it.Apr 29, 2025 am 12:42 AM

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.

Are there any alternatives to PHP sessions?Apr 29, 2025 am 12:36 AM

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

Define the term 'session hijacking' in the context of PHP.Apr 29, 2025 am 12:33 AM

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.
