I suggest you take a look at a session tutorial

And use CODE tags in your post to go around code! (have a look in the post bar where you can make text bold, italic etc)

Basic Guide to PHP Sessions:

Rule 1: Don't forget session_start();!!!

This is very important to use in the beginning every one of your pages that you want to carry the session to, because otherwise none of your $_SESSION superglobals will be accessible.

That's....about it. All of your variables held within $_SESSION can be most data types. Associative arrays, arrays, objects, strings, integers, etc....so you could have

Expand|Select|Wrap|Line Numbers

$_SESSION['userid'] = $_POST['user'];

When you want to "logout" you would unset the session variable

Expand|Select|Wrap|Line Numbers

unset($_SESSION['userid']);
