Stop asking the same question over and over again.
Either learn how to program, read some manuals, look up the individual statements you are having difficulty with... Or stop mucking about in code.

You have asked in every single post what a line containing "isset" in regards to some session variable does. You are blindly thrashing about and asking redundant questions. Stop doing that and actually learn a little bit on your own and come back with a real question.
Have problems with isset? Search php.net or google for it.
http://ca.php.net/manual/en/function.isset.php
Have a problem with sessions? Learn about them.
http://ca.php.net/manual/en/book.session.php
This is one of the most readily available forms of documentation that exists for any language and asking the same silly question about similar lines of code is a waste of everybody's time.
