When is a global not a global?

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? -- Nick Wilson http://performancing.com/user/1
