Answer 1

You're not in the same scope, as the header and footer files are included in a function's body. So you are declaring a local variable, and referring to another local variable (from another function).

So just declare your variable as global:

$GLOBALS[ 'var' ] = '...';

Then:

echo $GLOBALS[ 'var' ];
