Session Variables

[jean-yves]

Hi,

I'm just moving beyond basic PHP scripting to the more interesting stuff. I have a lot of experience with Active Server Pages using VBScript, and some things in PHP confuse me - ok, so lots of things in PHP confuse me, but this one is confusing me most at present 😉

In ASP, I just assign a Session variable thus:

Session("UserID") = 1234

Then I can just refer to it from any page, e.g.:

selectedUser = Session("UserID")

How do I do this in PHP? I follow the instructions in the books and php.net and nothing happens. I keep reading different explanations. Is there a simple and definitive answer?

Many thanks,
Jean-Yves

You will probably get many different answers here too.

Here is what I do.

session_start(); // required on every script that uses sessions

session_register("session_name");
$session_name = "the_value";

echo $session_name;

// check a session exists
if (session_is_registered("session_name")) {
.. yes its registered
} else {
.. no its not
}

// destroy all session
session_destroy();

// unregister one session
session_unregister("sessoin_name");

Hope this has put a bit of light on it for you.

p.s. I use to do ASP to, PHP is easy to pick up and better.🙂

Thanks for that! Appreciate all the various example snippets- just what I wanted.
