User Logging and sessions(?)

[s_shrum]

I have a site where I want users that will be inputting data to my DB to log in (free of charge) before I allow them to access the input forms.

WITHOUT using cookies, I want be be able, with sessions (I think), be able to do basic user authentication. I only need to pass 1 value around: user_id, which will be set when the user properly logs in.

Any code snippets that you can provide would be greatly apprechiated.

TIA

use:

session_start();
session_register("variable_name");

and you will see this variable in the array $_SESSION on any site on which you start your php code with session_start();

The variable can be i.e. login

Use session_destroy() to kill the session and
session_unregister("variable_name"); to log out
