上面是原字符串，为什么经过下面处理
处理后显示成这样，请注意?号后自动换行了，这里想不通

另外还问个问题，数据库中是这样存储的字符串
我
我
我

而经过',htmlentities($rw['content'],ENT_QUOTES,GB2312))) ?>这样处理后，显示成如下了
我
我
我
我
这里为什么会替换个空格呀，在里层的模式里加了\n就不会出现上面那种情况了
------解决方案--------------------
不用再求解了，这根本就不是问题，就算直接echo出来，？后面也会换行，浏览器把问号之间的字符串当一个单词处理，单词长度超过一屏就回换行，用word编辑英文的时候 一样的效果，所以仅仅是浏览器方面的原因
你可以在下面一段 随便插问号 然后调节浏览器宽度试试

What is a session in PHP, and why are they used?May 04, 2025 am 12:12 AMSession in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

What is the difference between absolute and idle session timeouts?May 03, 2025 am 12:21 AMAbsolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.
What steps would you take if sessions aren't working on your server?May 03, 2025 am 12:19 AMThe server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
