Solution

Some people say that becausesession_start(); statement, other html code exists, but

But some people say that his session_start(); It has been done before.

Some people say that it is not good to set the save path of the session, and it is necessary to modify the php.ini file:session.save_path = "C:/phpsession"

(The path behind is set by yourself, and make sure it exists)

• The php.ini file should generally be located under the system disk/Windows directory

LinuxCommand to query PHP configuration file path

The Linux command queries the storage location of the PHP configuration file php.ini file.

Execute under the shell:

php -v / -name php.ini

Or

find / -name php.ini

• Modify the php.ini file of the Linux server: session.auto_start = 0 for session.auto_start = 1
