RE: [Phplib-users] Why are my User Sessions didnt deleted if i lo gout ???

[Taylor, S. <Ste...@uk...>]

You dont need garbage collection because the aim of user session =
variables
is to remain persistant for the lifetime of each user (see my first
explaination)

Each user has one record in the user session table keyed on their user =
id.
When they first access the system this will be created new, and all the =
user
variables your application registers will be stored there with values
particular to that user (all squashed up into one long string).

If your application no longer requires a user session variable you can =
add a
call to unregister so that it will no longer be saved. =20

If user accounts are deleted from your application you can add a =
function to
remove the entry in the user session table for that user.

hey yes you are right !

But for what ???

shouldn=B4t be the user sessions deleted also when i logout ?

this could be a whole of garbage in the active sessions table

I really want to know if this is really right whats going on on my =
tables.
Because i was really confused about it. And i am reading this =
sourcecode a
few day=B4s to understand what it really do.

I am new to phplib and it is a few years ago that i am writing object
orrientet.
So please give me one answer is this really make=B4s a sense ?
