When is a global not a global?

[Nick Wilson <nick@xxxxxxxxxxxxxxxxxx>]

hi all, 

After upgrading a CMS, im having a problem with global variables not
showing up anymore -- configs and things could have changed, but search
as i have, i cannot find anything to help me work out what the problem
is. 

This should work of course:

    $foo = 'bar';

    function foobar() {
      global $foo;
      print(" ------ " . $foo);
      exit;
    }

    foobar();

It prints *nothing*. Does anyone have an idea as to what might stop this
from functioning as expected?
