Question

I have stored a session using the following in one of my .php file:

session_start();
    $_SESSION['uid'] = $_POST['uid']; 

When I navigate to some other .php file and tried to access the value by doing:

$_SESSION['uid']

I got an error:

Notice: Undefined variable: _SESSION in C:\wamp\www\saved.php on line 6

line 6 is:

$result->execute(array($_SESSION['uid']));

Why is this?

You need to make sure you call session_start() on every page on which you want to access session vars.
