Because you need to use shell_exec to execute python scripts in the project, under test shell_exec("test.py") can run normally without errors, but adding a directory shell_exec("python/test.py") will not work. Use For the PHP framework, I initially thought that the reason was PHP's directory limitation, but after trying to no avail, I found that it was not a directory problem.
So I thought maybe the shell_exec command does not support directories? A word awakened the dreamer, shell_exec is equivalent to command line execution
The code can be changed from the original
to the following picture, which is a perfect solution.

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.

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.

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.
