Hi everybody!
I have a problem and I was told to check out the sessions part in PHP.
What I want to deal with is the following :
I have a PHP page with a form, where the user writes some data. These data are then written into a file which is then used in a system command as input for an external program (NOTE: The data MUST be written into a file, it cannot be done elsewhise, because the external program takes a file as input).
The thing is that I must somehow create a file everytime a user enters data into the form, so I must learn something on sessions I think.
My question is, since I don't have a login system or something like that, but just want to create a different file each time (with the session_id being part of it, so that the file is unique), which session commands do I need?

It doesn't sound like you need sessions, but it's hard to tell from your description. HTTP is a stateless protocol; sessions are a workaround for that, a way to introduce continuity in a transaction consisting of multiple requests and responses. Possibly that's implicit in your requirement and I'm just missing it. At any rate, a session isn't permanent -- it has a limited persistence. If you want a user to generate a file today, and add to it tomorrow, you're going to need user validation.

The PHP Manual is the best place to start, for sessions or anything else.
