$_SESSION variable scopes

[BiggerBrother]

I thought this was an easy thing that I over looked, and after a long week, and now wanting to quit for the weekend, I can't seem to see the wood for the trees!

I have a function, and within the function I refer to a session variable. I've tried echoing out the variable, and I don't get anything, when I know that the session is populated. What am I missing? The function is called by another function, which is in an included file.

Within the function I just have echo "this is the variable" . $_SESSION['variable_name']; , and it only returns the "this is the variable" bit.

Any help would be gratefully received.

Many thanks

BB

either the variable is not set ;> or the session has not been started or both.

I agree.

$_SESSION is a superglobal array. Superglobal variables are, by definition, available in every variable scope.

So either the element was not set or the entire array was not instantiated.

You could try using: error_reporting(E_ALL), and run the script.

If the session has not been started you will get a
Notice: Undefined variable _SESSION: in...

If the session has been started but the variable within the session array does not exist you will get:
Notice: Undefined index: variable_name in...

This should tell you where the problem lies.

Many thanks for your responses. It now works perfectly.
