不要在php5.3下运行dedecms5.6版本
今天在利用dedecms结合ecshop帮公司制作分销联盟的,发觉dedecms5.6在php5.3的环境下连续出错
deprecated in include\dedesql.class.php on line 516 Deprecated: Function eregi() is deprecated in include\memberlogin.class.php on line 45 Deprecated: Function eregi() is deprecated in include\memberlogin.class.php on line 45 Deprecated: Function eregi() is deprecated in include\memberlogin.class.php on line 45 Deprecated: Function eregi() is deprecated in include\dedesql.class.php on line 270 Deprecated: Function eregi_replace() is deprecated in include\dedesql.class.php on line 270 Deprecated: Function eregi() is deprecated in include\dedesql.class.php on line 516
根据报告,发现原来php5.3已经不在支持eregi和eregi_replace
技术比较好的,可以下载dedecms5.7,我有些文件也是直接从dedecms5.7抄过来的,因为5.7版本已经开始支持php5.3了
解决方案如下:
* call_user_method() 可以用 call_user_func() 替代
* call_user_method_array() 可以用 call_user_func_array() 替代define_syslog_variables()
* dl() 反对在使用DL加载扩展,php5.3 以后应用php.ini配制
* ereg() 可以用 preg_match() 替代
* ereg_replace() 可以用 preg_replace() 替代
* eregi() 用 preg_match() i 参数替代
* eregi_replace() 用 preg_replace() i 参数替代
* set_magic_quotes_runtime() 用 magic_quotes_runtime() 替代
* session_register() session_unregister() session_is_registered()
* 以上三个统一用 $_SESSION 替代
* set_socket_blocking() 用 stream_set_blocking() 替代
* split() 用 preg_split() 替代
* spliti() 用 preg_split() 模式 ‘i’ 替代
* sql_regcase()
* mysql_db_query() 用 mysql_select_db() mysql_query() 替代mysql_escape_string() 用 use mysql_real_escape_string() 替代
* 关于时区处理,统一用Timezone对像

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.
