图片可以base64编码后以字符串的形式发送给服务器去处理，但是为什么不能直接传呢？不考虑传输的数据量大小及可行性分析，仅仅对这个问题的求解

sure，为什么不能提交？只要你随便测试下便知道的结果。

电脑上的图片是【纯二进制数字】在个人电脑的另一种技术显示方式，就是将这些数字翻译成点阵图形(类似字符编码)或者矢量图形(增强类型的图形技术)，你通过html表单发送过去的是【字符】！除非你对接收的字符进行处理，通俗讲翻译成【图像】，否然你只看到还是【字符】，永远和【图像】莎哟啦啦....

为什么不能直接传呢？

可以直接传啊。

正常的做法都是binary data直接传啊，base64编码白白增加开销。

What is a session in PHP, and why are they used?May 04, 2025 am 12:12 AM

Session 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 AM

Absolute 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 AM

The 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.
