Are you there? PHP cannot understand the modification of session and cookie!

Are you there? PHP cannot understand the modification of session and cookie! Check whether SESSIONID has been modified for the following two functions. Why can't I get the correct id? Each time the browser generates a fixed id, the id I get is changing.

Terrible

Are you talking about me ......

Lots of if else

I mean, the person who writes this code is so funny.

A bunch of if else phpthink

I mean, the person who wrote this code is too funny to write phpthink.

Thinkphp, phpthink from there

Thinkphp, the phpthink from there. I am right here to help you.

Isn't this a built-in function of thinkphp?
What do you want to do?

What do you want to do? The problem still persists. I suspect that it is not a client program, but the internal mechanism of thinkPHP.

Can you access it in a browser?

Can you access it in a browser? Yes.

It means there is something wrong with your client.

It indicates that your client has a problem, but the php backend has modified the session and cookie.

Whether or not the backend has modified the session and cookie
As long as the browser can be normally accessed, it means that the system works normally.
This proves that your client has a problem: the cookie cannot be obtained correctly.

Is the problem clearly described?

As long as the browser can be normally accessed, it means that the system works normally.
It also confirms that your client has a problem: the session generated by the browser is not fixed when the cookie is not obtained correctly! However, I have fixed it here. I checked it and said it was a thinkPHP problem. the configuration file php. ini was modified, and it was invalid. so I think it was a php backend problem.

Is the problem clearly described? I don't understand where it is.

The session is generated by the server. as long as the browser does not leave the website, the session id will not change.

Thinkphp sessions are also called based on the php session method.

session_id();

Isn't this a function for modifying sessionid?

You 'd better read it with another post from the landlord!
The landlord wrote a simulated login program in C #, and the login status cannot be maintained.
Therefore, thinkphp is suspected to be a problem.

Your client only needs to be able to correctly read and send cookies.

Your client is onlySimulationBrowser behavior

Your client is onlySimulationBrowser behavior! But no one answered questions in Section C ......
