Then browse B. php to get the session value written by a. php. Empty!

Why? The test is normal on the local machine. The upload server is complete.

Session information of PHPINFO

Session. save_path D:/hosting/user/html/temp

This folder is readable and writable.

When you browse the. php page, a large file is generated and the session value is saved.
When you browse the B. php page, a file of 0 size is generated. Not available? Why?

   $_SESSION['session_value'] = 'value';
   
var_dump($_SESSION);
