Ok there is the thing.
with php you don't declare a global variable with global $var. when you
use global you say 'I wanna use this $var in my function even if it has
been declared in superior scope'.
For example :
function say_hello()
{
global $hello;
echo $hello;
}
say_hello();
$hello = 'hi';
say_hello();
This script will echo nothing and hi, because the second time the
variable has a value.
I think you see this in a C/C++ way. That's not PHP's way.
another thing. when you write global ${'affiliations_'.$i.'_nid'}, it
can't be good, $i is not even declared at this point.
