Hopefully a quick question about the session_cache_expire( ) function. If I understand correctly, If I set the session_cache_expire(20), does this means that twenty minutes afterwards the session will expire? Also, does setting the session_cache_expire(20) also sets the cookie, i.e. setcookie("PHPSESSID","",time( ) + 20,"/");, so one can skip the setcookie("PHPSESSID","",time( ) - 1200,"/"); when ending/unsetting a session? Thanks in advance for your help.
