Opening a php session from another language (Java, ColdFusion).

[balteo]

Hello,
I am currently working on a portal that will most certainly use several programming languages (PHP, Java and CFML). I would like to open a php session from one of the above languages and possibly maintain the PHP session with up-to-date values as the user navigates the site in JSP/Java. Is this possible in PHP? Can anyone give me some clues?
Thanks in advance,
Julien.

I honestly don't know for sure but my guess would be no because of what a session is.

A session is a cookie on the user's machine that stores a link into a file on the server.

Now if all the languages use the same place to store the server side files and all the languages use the same layout then this is possible. Otherwise it is not.

I would recommend that you either run tests or you read the white paper on sessions.

What you can do is use cookies to store the info instead of sessions then this becomes not only possible but trivial.

I have to ask though why the various languages?

php defaults to saving session data in files, but can be configured to save that data to a database. You could also write your own functions to handle this.

read the manual on sessions and look for session_set_save_handler.

I'm also curious as to why you must use different languages. Are you using more than one server or are they on the same server?

The reason I am going to use multiple languages is that I would like to use existing code (eg phppp) and integrate it with what I have coded in java.
