PHP: what is the purpose of session_name

Question

I\'m not quite sure what the purpose of session_names is.. Can someone please explain in what circumstances defining a name would be beneficial?

Answer 1

The default is - I think - PHPSESSID. If you have more than one application on the same host, they would share those sessions. So, you should set different session names for each application, so that there is no weird stuff happening.
