sessions

[F_SH]

Right, so I have a login page for a user. He comes, gives his name and password. This is checked on a database and I want to give the person free range on my site.
I also want the user to identify himself to every page. When I used ASP, I did this with sessions. I assume there is something similar with php? What are the functions to start a session, end a session, write x to y, y being a session variable and then read y into x?

Many thanks

PS can't find many tutorials on this, and those I do seem to show differnt stuff. In any case, it never worked..

guess what they're called? That's right, they're called sessions.

and the best place to find out about them? the manual!

yeah, that was one of the first sources. What it said didn't seem to work...

I also can't see how to extract information from the session variables there.

read the bit about "registering a session". once a session is registered, you access it in the same way as you do in the code there:

<?php
session_start();
// Use $HTTP_SESSION_VARS with PHP 4.0.6 or less
if (!isset($_SESSION['count'])) {
    $_SESSION['count'] = 0;
} else {
    $_SESSION['count']++;
}
?>

so you would just do something like

echo $_SESSION['count']

to get to it

I agree with John that you need to look at the frikin' manual.

http://www.php.net

An example from there is this:

<?php
session_start();
// Use $HTTP_SESSION_VARS with PHP 4.0.6 or less
if (!isset($SESSION['count'])) {
$SESSION['count'] = 0;
} else {
$_SESSION['count']++;
}
?>

ALSO KEEP IN MY YOU MIGHT WANT TO USE COOKIES.

setcookie();
is a function to remember and lookup.
