make a <? phpinfo() ?> file -- it will explain what PHP was compiled with up
the top-ish.

By default, sessions will work with cookies (at least every install i've
seen)... you don't need to do anything special to get it working. *IF* you
are worried about people without cookies not being able to maintain the
session, *THEN* passing the SID around in URLs would be the next step. You
can do this manually (a lot of work), or...
*IF* enable_trans_sid() was compiled (or if you can comile with it), this is
the best option, because everything happens transparently... IF the user
allows cookies, PHP will use them... if not, PHP will re-write your URLs
with the SID in them.
Easy.

Assuming PHP >= 4.1.1 with register globals OFF, and cookies ALLOWED by your
browser OR trans_sid compiled:
page 1:
<?
// maintain or start session
session_start();
// assign a few variables to it
$_SESSION['favcolor'] = "#FFCC99";
$_SESSION['name'] = "Justin";
?>
<HTML>
<BODY>
<A HREF="page2.php">click here to see page 2</a>
</BODY>
</HTML>
page 2:
<?
// maintain or start session
session_start();
?>
<HTML>
<BODY bgcolor="<?=$_SESSION['favcolor']?>">
Hi <?=$_SESSION['name']?>, hopefully this session carried forward.<BR>
<A HREF="page3.php">click here to see it carried to page 3</a>
</BODY>
</HTML>
page 3:
<?
// maintain or start session
session_start();
?>
<HTML>
<BODY bgcolor="<?=$_SESSION['favcolor']?>">
Hi <?=$_SESSION['name']?>, hopefully this session carried forward to
the third page.
</BODY>
</HTML>
Good luck,
