Well, it's a source of many troubles, misunderstanding and tricky "walkthroughs",
so I'll try to explain what's exactly going on there.
History first. More than a year ago there was a discussion in the list on
possibility of adaptation of session class to PHP4 sessions. This
brought to us 3 (three!!!) implementations of native sessions with
PHPLib API. The first was by Teodor Cimpoesu, who, as he noted, did a
quick and dirty hack to show that this is possible. The class was
mainly old session class with some parts changed to calls to PHP4
session API, the other parts (storage, SID propagation and such) just
commented out. The second was by Barendt Scholtus (excuse me, Barendt,
if I misspell), who did the similar job to Teodor, but also changed
user.inc and page.inc in the similar way. He named his effort as
phplib4, and it remains by that name in the CVS now in the unsup
directory. Both implementations just used to be simple and limited wrappers
over PHP4 session module, conforming to the PHPLib API.
Then, I introduced my session4_custom, which was almost fully
rewritten implementation, which was intended not only to conform to
the PHPLib (public) API and use native PHP4 session module, but also provided a
custom save handler, which used PHPLib's CT_*-style containers as a
session data storage, and an interface to the php.ini's session module
settings from within the Session class. Session4_custom could not only store
data in the CT_* containers (custom save handler), but also use native save
handlers - files, mm and so on. Also, because of the incompatibilities
of the new session4_custom with the old User class ideology, I
introduced the new rewritten User class - User4, which was no longer depend on
Session, with compatible public API but very different guts.
Prepend.php & page.inc were also changed a bit to reflect the session
changes.
Then, Ulf Wendel came and said he need clean and working class
urgently. He began to hack session4_custom. He splet the
Session4_custom class in two parts, the first class with common session API
(now in session4.inc), the second with the custom save handler (now in session4_custom.inc),
which extended the first.
As a result, the Teodor's class had been acquired by the new Session4
class, the session4_custom was simplified, both were put to
php-lib/php/session CVS directory, and Barendt's phplib4 moved to unsup
directory.
So, there's two implementations of PHP4 native sessions in the PHPLib
CVS - session4.inc & session4_custom.inc in the php-lib/php/session
and phplib4 stuff (I see it in various places), which is not mine.
By the way, the docs at Tarique's site concerning PHP4 sessions
(http://www.sanisoft.com/phplib/manual/php4_sessions.php ) are all
about phplib4.
