Preserve website data

[misxa]

Hi!

I'm working on a login script as a part of a website, and I, as many of you have, have run into dillemas:

• How to store data that could be available in all pages?

• I've tried with sessions: Data were stored in /tmp directory correctly, but I don't know if those data are visible across all pages, and if they are, how can I use them (what's the scheme?)?

I would be endlessly grateful if anyone of you would help me solve my dillemas, and explain the scheme, or at least, give me a link to similar sollutions.

Thanks,

Milan.

To use a session, you must first have:

session_start();

At the beginning of your page. I think that older versions of PHP require that the session ID be passed by URL, but with the latest version of PHP (I never used sessions before then) I was able to pass sessions without doing this.

Then, you simply access a session variable like this:

$_SESSION['session_name'];

The other way is to use a cookie, which isn't a bad idea. However, I would recomend sessions.

I hope I was able to help. I apologize if I failed to do so.
