PHP $_SESSION empty after header redirect

Question

I\'m losing the data in $_SESSION when I do a header redirect. When I walk through this with a debugger I can see all my data in $_SESSION before I exit();

You should call session_start() on every page accessing (that is, reading or writing) $_SESSION, and call it before any access to the session array. So, be sure you call session_start() on both pages.
