First of all i am new to PHP Session.
I do session_start(); command at the begening of every page so that php uses session but what i also what it to do is that if that person closes the browser and returns back to same website it should atleast pick up the person's user name so that they dont have to type it again and again when ever they come back. plus to that every single time that person close the browser and come back to that website it creates a new session which is painful as each session take space on the webserver. any idea on how to get the php to get the session id of an old session that was made by the same website and run that session if it is available. any tips on session is good as i was not able to find good documentation on php.net regarind this problem.
