php5.3不支持eregi()函数了

写正则的时候可能会碰到用ereg()时出现错误,如:Deprecated:   Function eregi() is deprecated ××××××××,原因就是php5.3已经不支持ereg(),可以用preg_match() i 参数替代,比如:ereg(“^[[:alnum:]]+$”, $pass); ——>   preg_match(“/^[[:alnum:]]+$/i”, $pass); 

以下是详细说明: 

php 5.3 从一方面来讲,可以说在07年计划PHP6的中的一个pre版本,增加了很多功能,统一了很多语法,使PHP变得更加强大与简洁。 

说到统计架构规划,PHP当然会对一些别名,重复功能function进行归类整理,并把一些不用的正式在php 5.3以后删除掉.故不建议在新项目继续使用. 

PHP 5.3 有两个deprecated, 

E_DEPRECATED and E_USER_DEPRECATED 

以下是在旧的项目中会在php 5.3以后碰到的问题 

* define_syslog_variables 
* register_globals 
* register_long_arrays 
* safe_mode 
* magic_quotes_gpc 
* magic_quotes_runtime 
* magic_quotes_sybase 
* 在PHP.ini 注释用#已经不再建议使用. 

Deprecated functions: 

* 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 


Deprecated features: 


* 直接返加new 实例不再建议使用. PHP 6 将不再支持 
* Call-time pass-by-reference 参数现在不再建议使用 PHP 6 将不再支持 
* 用 {} 访问字符串顺序不再建议使用. 统一用 [] 代替. PHP 6 将不再支持 


当然如果项目紧急,又要在php 5.3 使用以上方法,可以用下面的方法去做 
在php.ini 增加 

php_flag allow_call_time_pass_reference On 
php_value error_reporting “E_ALL & ~E_NOTICE & ~E_DEPRECATED”

What are some common problems that can cause PHP sessions to fail?What are some common problems that can cause PHP sessions to fail?Apr 25, 2025 am 12:16 AM

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

How do you debug session-related issues in PHP?How do you debug session-related issues in PHP?Apr 25, 2025 am 12:12 AM

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

What happens if session_start() is called multiple times?What happens if session_start() is called multiple times?Apr 25, 2025 am 12:06 AM

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

How do you configure the session lifetime in PHP?How do you configure the session lifetime in PHP?Apr 25, 2025 am 12:05 AM

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.

What are the advantages of using a database to store sessions?What are the advantages of using a database to store sessions?Apr 24, 2025 am 12:16 AM

The main advantages of using database storage sessions include persistence, scalability, and security. 1. Persistence: Even if the server restarts, the session data can remain unchanged. 2. Scalability: Applicable to distributed systems, ensuring that session data is synchronized between multiple servers. 3. Security: The database provides encrypted storage to protect sensitive information.

How do you implement custom session handling in PHP?How do you implement custom session handling in PHP?Apr 24, 2025 am 12:16 AM

Implementing custom session processing in PHP can be done by implementing the SessionHandlerInterface interface. The specific steps include: 1) Creating a class that implements SessionHandlerInterface, such as CustomSessionHandler; 2) Rewriting methods in the interface (such as open, close, read, write, destroy, gc) to define the life cycle and storage method of session data; 3) Register a custom session processor in a PHP script and start the session. This allows data to be stored in media such as MySQL and Redis to improve performance, security and scalability.

What is a session ID?What is a session ID?Apr 24, 2025 am 12:13 AM

SessionID is a mechanism used in web applications to track user session status. 1. It is a randomly generated string used to maintain user's identity information during multiple interactions between the user and the server. 2. The server generates and sends it to the client through cookies or URL parameters to help identify and associate these requests in multiple requests of the user. 3. Generation usually uses random algorithms to ensure uniqueness and unpredictability. 4. In actual development, in-memory databases such as Redis can be used to store session data to improve performance and security.

How do you handle sessions in a stateless environment (e.g., API)?How do you handle sessions in a stateless environment (e.g., API)?Apr 24, 2025 am 12:12 AM

Managing sessions in stateless environments such as APIs can be achieved by using JWT or cookies. 1. JWT is suitable for statelessness and scalability, but it is large in size when it comes to big data. 2.Cookies are more traditional and easy to implement, but they need to be configured with caution to ensure security.
