Variable scope issue

I have a function foo () in a file called funcfoo.php called from my main
program file main.php, which has an include for that file.

Foo () contains a line:

echo $bar;

Now I have a (global) variable $bar which is set in main:

GLOBAL $bar;
$bar = 1;

When I call foo () from main it doesn't echo the value 1. (How) can I make
$bar visible to foo () without explicitly passing it as a parameter ? Is the
only way putting the entire foo function body in the same file as main ?

TIA

It has no effect to use the "global" modifier in the global scope.

Variable scope and the use of global is very well explained here:

Try using GLOBAL $bar; in function foo() before the echo. This is all
explained in http://www.php.net/manual/en/languag...bles.scope.php
