Session ID not working - help

[Anon]

Below code is from php manual :

<?php
session_start();

<php?

the <?=SID?> is necessary to preserve the session id

in the case that the user has disabled cookies

?>

To continue, <A HREF="nextpage.php?<?=SID?>">click here</A>

i want to propagate session id through URL but There is nothing for SID.......what happen ??

if i try to display SID , "echo $SID", also
nothing...i can echo $phpsessid.....
which variable will php engine want ?
SID or PHPSESSID ???

thanks for ur help

Hi Mike,
Try appending PHPSESSID=$PHPSESSID
i.e ...../abc.php?PHPSESSID=$PHPSESSID

Remember to start session on each page you want to use this session.

Ajay, thanks.

i wondered why i cant get this in php.net.
they still show <?=SID>.

Any where i can refer more on that ? no point
for me to get all the outdated documentation.

Yeah, I see that code on ref.session.php

My question is... since when was
=CONSTANT
valid code anyway?
