S> PHP4.3.10: S> else, test: S> else, sesstest: S> test: S> sesstest: S> else, test2: S> test2: S> I don't understand, why the variables seem to be empty. Dump out the session contents and see what's in there (if anything): print_r($_SESSION); Equally, dump out the cookie super global to see if the session cookie even got set print_r($_COOKIE); Or use the Web Developer extension for Firefox and "Display cookies" after the first page load - you should see the PHPSESSID cookie in existence. If not, that's the problem. If so, what does it say? S> In the session_is_registered-part, the var seems to be empty, too. Why? Because even 4.0.6 shouldn't be using that function. If you want to check for the existence of a variable, use isset().
