Here is a nice problem. I have two scripts, one calling the other with via
an include. The script that is included contains a variable, a function and
a call to that function. The variable needs to be accessible to the
function, so I declare it having a global scope. Then I execute the
function, which should echo the value of the variable. Contrary to what I
expected, the variable isn't there.

The code of the 2 programs is:

script1.php
<?php
function blah()
{
include("script2.php");
}

blah();
?>

script2.php
<?php
$foo = "bar";

function blahblah()
{
global $foo;
echo $foo;
}

blahblah();
?>

I can't see anything wrong with the way I set this up, even more since a
call to script2.php does exactly what it's suppossed to do: echo the value.
What's going on here is beyond me. Anybody has a clue?

Kind regards, Maarten
