Beware the problem that davo971 AT gmail DOT NO DAMN SPAM COM demonstrates can also happen in the
following case:
index.php
<?php
include("test.inc");
?>
test.inc
<?php
function foo() {
global $bar;
echo $bar;
}
$bar = "Hello World";
foo();
?>
This prints nothing.
if you add global $bar at the start of test.inc it will work just fine.
