I am to build a PHP application for a website that already has another PHP application running on the same domain/server. My app will of course be using sessions, and I don\
Another thing that may help you in keeping apps separate is move the session storage to another place either setting session.save_path
in php.ini to a folder of your choice or calling session_save_path() before session_start().
There is an easier way: session_name.
Prior to calling session_start();
call session_name("something"); (where you change something to whatever you want it to be called).
