set session.save_handler and PHP 7.2

Unable to set session.save_handler in my code

ini_set(‘session.save_handler’, ‘user’);

As I see in php.ini, the default value is “files”. I try to change the value to files, but it’s the same. Until PHP 7.1, everything works fine, but on PHP 7.2 and PHP 7.3, I have this problem. I really can’t understand why this function not working. It doesn’t return any error, just a blank page with code 200 (not 500 as server error).

Use session_set_save_handler () function will save the session to the MySQL database

Setting session_set_save_handler for one page only



As of PHP 5.4 you can revert to the default session handler by instantiating the SessionHandler class directly:
