Session and function

[Anon]

I'm having problem dealing between session and function, which need to make the variable globalize.

//session_register(""user_name", "password")

//Running function
idle_time()
{
session_start();
if(empty($user_name) || empty($password)...
}

The session in the function sounds doesn't work.. anyway to work this out huh??

I've never tried using session_start() inside a function.
If you start the session outside of the function (in the main page or a file included in the main page) then you can use session variables within the function as long as you define them as global variables or pass them to the function:

function idle_time() {
global $user_name, $password;
if(empty($user_name) || empty($password)...
}

or

function idle_time( $user, $pass ) {
if(empty($user) || empty($pass)...
}

If you pass the variables to the function using the function parameters, remember that you have to call the function like 'idle_time( $user_name, $password)' but you can simply call it like 'idle_time()' if you define the variables as global within the function.

Hope this helps!
