Unable to set session.save_handler in my code

https://stackoverflow.com/questions/55785829/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

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

Note that elseif and else if will only be considered exactly the same when using curly brackets as in the above example. When using a colon to define your if/elseif conditions, you must not separate else if into two words, or PHP will fail with a parse error.
