PHP 7.2 Warning: “Cannot change session name when session is active”

Question

Since PHP on our server was upgraded to 7.2 from 7.0. I am getting the following warning (which leads to error) if a new deployment is done. The reason is probably, that old

I had a similar problem but finally found a way through. The code below was my first approach that gave me errors.

static function startmysession($lifetime, $path, $domain, $secure, $httponly){

    session_set_cookie_params($lifetime, $path, $domain, $secure, $httponly);
    session_regenerate_id(true);

    if(!isset($_SESSION)){
        session_start();
    }
}

Now Earlier versions of php overlooked our mistake(We were practically renaming and giving a session that already exists properties which is very wrong. So how did i solve this problem?

static function startmysession($lifetime, $path, $domain, $secure, $httponly){      
    if(!isset($_SESSION)){  
         session_set_cookie_params($lifetime, $path, $domain, $secure, $httponly);
         @session_regenerate_id(true);    
             session_start();
         }    
    }

I now bound the session_set_cookie_params() just before session start and I test if the session already exists before doing so.
