include() and scopes

Hello,

given the following scenario, how can I make _a visible in 3.php? Below is
what I /tought/ would work...

1.php:
global $_a;
$_a = 42;

2.php:
include('1.php');
include('3.php');
foo();

3.php:
function foo() {
print $_a; //prints nothing
}


TIA,
Mitja

Declaring a variable as global outside of any function (as you've done)
does nothing.

Move the "global $_a" declaration into the foo() function.
