翻出来源码开了下，字符串中使用换行的方法为"Name:{$name}\nAddress:{$adress}\nCity:{$city}\nCountry:{$country}\n ......"
既然"\n"起不到换行的目的，修改成"\r\n"看看.
修改 =》提交＝》测试
得出的结果还是没有换行！！！！
难道是操作系统兼容问题？？
直接使用php runtime 常量 PHP_EOL 替代 "\r\n"
修改 =》提交＝》测试
得出的结果还是没有换行！！！！
什么情况？不可能这个也解决不了操作系统兼容性问题的换行符号。
看看到底这个xls文件是怎么用php生成的。
看了下生成excel的代码，Oh My Lady gaga，原来是用html的格式，只是文件后缀写成xls，既然html的格式，那么应该
可以起到换行的效果吧。
继续
修改 =》提交＝》测试
结果是可以换行了。可喜可贺啊。问题终于解决了。
告诉老大问题解决，此时心中甚是喜悦啊。

过了一刻钟的样子，老大跑过来说：“换行效果的问题是解决了，但是你看下，数据不好复制了。”
。。。。
省略沟通N句。
把一个单元格的数据复制下，然后粘贴到 word中。Oh My Lady gaga, 为啥会有border？？？？
到底什么问题？？使用\n、 \n 把不能起到换行的相关,使用
把效果是有了，但是又出现了新问题。。。到底如何是好？
没辙了，使用BAIDU google吧。
终于黄天不负有心人，找到了问题的答案。

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?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?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?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?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?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?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)?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.
