Help with conflicting sessions

[Dave]

Hopefully this is an easy question for those with more experience.

I have two separate programs that I want to use together on a website

Program A starts first and calls session_start() .

Program B is started by the user clicking on a link and it also calls
session_start() .

The session started by program B blows away the session started by program
A and program A will not work any longer.

How can I have two independent sessions that don't interfere with each
other?

Any advice or code snippets would be appreciated.

Thanks,
Dave

What you calling "programs" at first?

Program A starts first and calls session_start() .

Program B is started by the user clicking on a link and it also calls
session_start() .

The session started by program B blows away the session started by program
A and program A will not work any longer.

Can you please illustrate it in more presentable way?
I can't understand, how it is possible.

How can I have two independent sessions that don't interfere with each
other?

They are independent for sure.
Even more, new session will be started every time until you start to store
something in it.

Any advice or code snippets would be appreciated.

Kidding? You haven't explained anything, you haven't provided any example
illustrating your problem...
What do you expect from us? We not gonna do your work for you.

I don't want anyone to do my work for me, that's not it at all. Sometimes
a picture is worth a thousand works and a code fragment might make a
concept clearer than a narrative.

There are two working html files using PHP that I am trying to bundle
togther on one webpage using frames. The outer frame is the main part of
the page but it requires you to login and it creates a session. The
inner frame is a web-based email program that also requires you to login
and authenticate and it starts a session. This session seems to
overwrite the original one and the main program no longer works.

The question is: is there a way to establish two independent sessions
from one html/php script?

Thanks,
Dave

Dave,

Are you looking at the same domain? If so, they should have the same
session. But that shouldn't be a problem - just store the variables you
want in the apporpriate $_SESSION values (use arrays within the
$_SESSION array to keep things cleaner).

If they are two different domains (remember - www.example.com and
example.com are considered "different" by default), you should already
have two sessions.

But without any code, it's hard to tell what you're doing. So it's even
more difficult to see what's wrong.

One thing to note is that sessions are lost when the url is not
relative, see here:
http://us.php.net/manual/en/session.idpassing.php

Also if you are accessing session from included files the way they are
called can lose the session. For instance if url includes are allowed
and you do from a file with session_start() already called:
include "/var/www/htdocs/file1.php";
include "http://sameSite/file2.php";

the session will be available in file1 but not in file2

That's only if you're not using cookies. When using cookies (which
virtually everyone does), absolute or relative urls are immaterial - as
long as the domain itself is the same.

Also if you are accessing session from included files the way they are
called can lose the session. For instance if url includes are allowed
and you do from a file with session_start() already called:
include "/var/www/htdocs/file1.php";
include "http://sameSite/file2.php";

True, if you do a url include. However - why would you ever do that on
your own site? It requires an additional call to the server and
additional server processing. It's much better to include it as a file
- in which case the session information is available.

Thanks to all for their repsponse. I will work on some code changes for
next couple of days based on your input.

You could just use session_name() to set two different sessions.

so like:
session_name("p rogramA");
session_start() ; /* your $_SESSION variable are now for programA */

and in your other 'program'

session_name("p rogramB");
session_start() ; /* your $_SESSION variables are now for programB */
Although, surely you can just use different variable names in one
session??
