There is a problem with PHP session, how do you get back? Beginner, would you please help me?

I used to, but after we changed it, Session.save_path = "D:/session"
This is the case, but also ask you to help the great God, thank you!

There was??? before the session. Go ahead, check your generation. Ruled out

Please check if the Session directory is present under the D drive.

Does the d:/session exist and have limitations??

Before changing the session can be used, the code has not changed Ah, the front of no output on a header (...)
Session file exists on D disk
Permissions are root

Why change the value of Session.save_path, change back to try.

What is the default value? Forgot.

The default value for Session.save_path is/tmp, which is the temporary file directory of the operating system
Can not be set (comment out Session.save_path)

If set, you must ensure that the directory has full control of the general user

As long as there are session_start () files will appear this situation, remove the session_start () on it. Comment out the configuration file and change the "d:/session" to/tmp or not, where is the problem? Was that a problem before?

It seems that there is no output in front of session_start ()

It seems that there is no output in front of session_start ()

There is no output, previously can be used, now do not, do not know whether to change the session of the path problem
