I'm not the admin on the server, so I'll have to manage with
the software
provided. And that is php 4.0.6.
Ah, right. Me, too, actually, which is why I still have the 4.0.6 manual on
my PC!
I've tried a number of ways to store variables in the session
file. This
works:
session_start();
$foo = 'bar';
session_register('foo');
then after session_write_close(); or end of script:
echo $HTTP_SESSION_VARS['foo']; will output 'bar'.
just adding variables directly into the HTTP_SESSION_VARS
array won't make
them stick in the session file.
No, I wouldn't expect them to as the manual explicitly says they won't.
Use of session_register() seems to be
required.
Yes. I'd expect that too -- the 4.0.6 manual is again quite clear that you
can only get variables into your session with session_register().
What it's not so clear about is whether
session_register('foo');
$HTTP_SESSION_VARS['foo'] = 'bar';
will set the session variable foo to 'bar' under all circumstances -- it
im-plies that it should when register_globals is off, but is very ambiguous
about exactly what happens when register_globals is on.
Thanks for the heads-up on this topic -- I'm just about to start writing
some code which will make heavy use of sessions, and initially it will have
to work for version 4.0.6 (until my site admin decides to upgrade), so I
guess I've got some heavy testing in prospect on my test server to work out
exactly what all the combinations do -- I need to write stuff that will work
regardless of register_globals, and will continue to work unchanged when the
eventual upgrade to 4.3.x comes along.
Cheers!

ok, so now the variable names are registred and stored in
the file. But
without values.
check this:
--firstpage.php
session_start()
session_register('foo');
$HTTP_SESSION_VARS['foo'] = 'bar';
echo $HTTP_SESSION_VARS['foo']; //outputs bar;
transport by a href to:
secondpage.php
session_start();
echo $HTTP_SESSION_VARS['foo']; //outputs nothing
---
checking the contents of the file called /tmp/sess_{session_id}:
!foo|
(snip)
Make a choice here..
= session_register('foo');
= $HTTP_SESSION_VARS['foo'] = 'bar';
Use either the session_register() function or the session
global array. Not
both.
Not true -- $HTTP_SESSION_VARS is *not* like $_SESSION, and its values are
*not* auto-registered. In fact, I still have my copy of the 4.0.6 manual
around, and it specifically gives this as an example:
Example 1. Registering a variable
?php
session_register(count);
$HTTP_SESSION_VARS[count]++;
?
However, it's a little unclear on whether this should still work
regardless of the register_globals setting, as it also gives this as an
example:
Example 2. Registering a variable with register_globals enabled
?php
session_register(count);
$count++;
?
I guess I'd have to go away and try it to be sure of what behaviour occurs
for each setting of register_globals -- but there seems little point given
that using $_SESSION has been much the best option for several versions now!
Cheers!

After creating a new session with session_start() and
inserting a few values
e.g $HTTP_SESSION_VARS['foo'] = 'bar'; a file
/tmp/sess_{session_id} is
created.
The problem is that this file is empty! 0 bytes. no data is stored.
I'm using php 4.0.6 on linux with apache 1.3 something.
Just doing session_start() will create the file. Are you also
session_register()-ing your session vars? The $HTTP_SESSION_VARS array
isn't like the $_SESSION array introduced in PHP 4.1 -- it's values are not
automatically registered. You still have to use session_register(), thus:
session_start();
session_register('foo');
$HTTP_SESSION_VARS['foo'] = 'bar';
HTH

Check the register_globals setting in php.ini. If it is set to On, then
code like this:
session_start();
$foo = 'bar';
session_register('foo');
echo $foo;
If register_globals is set to Off, then code as you are already doing:
session_start();
$HTTP_SESSION_VARS['foo'] = 'bar';
echo {$HTTP_SESSION_VARS['foo']};

I guess it should be something like !foo=bar|
but, as I said, the values doesnt seem to stick in the file, just the names
of the variables.
I must be doing something wrong.

Re: [PHP] session data missing
ok. now I get it. first set the session-variables like any other:
$foo = 'bar';
then register them in the sessionfile:
session_register('foo');
that makes sense. But it's not at all what the manual says. I guess my php
version has passed its expiration date.
thanks for the help, anyway. It seems to be working the way I wanted it to.
