问题 I'll be working soon on a project and I just wanted to ask this before. The project is on symfony 2.8 with php 5.4. The goal is to upgrade symfony to 3.4 (maybe 4.x later) and php to 7.x (probably 7.2). So here is my question : is there a better order to do this?

问题 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 sessions get invalid after deployment. Warning: session_name(): Cannot change session name when session is active in /var/www/html/model/login/lib/Session.class.php on line 137 Warning: session_set_cookie_params(): Cannot change session cookie parameters when session is active in /var/www/html/model/login/lib/Session
