All the tutorials say to put session start. They don't say if that should be in all pages on the website, or some, or only 1.

And if it's only 1 page, does it have to be the main page? Or a page with a form that I am making that puts the session ID in the database? If the visitor never visits a page with a session id but they are on the site, do they still have a session id?

You need to put this in each page that need to access the session data before accessing (or creating) any session data.

See: http://php.net/manual/en/function.session-start.php
