[About passing arguments to functions and global scoping]
Declaring $id global:
function doit() {
global $id;
echo $id;
}
$id = 1;
doit();
output is 1
Passing $id as parameter:
function doit($input) {
echo $input;
}
$id = 1;
doit($id);
output is 1
See the sections of the manual on Functions and variable scope for more
information.

If you want to access id, you know that it is available as $id; but if
you want it accessible within the function, you either have to pass it to
the function as a parameter or delcare it as global within the function.

SV: [PHP] Including files without loosing my string
Thats only if i call the index.php file first.
For that i have another solution
if (function_exists('func')) {
call_user_func ('func');
} else {
include 'main.php';
But thats not the problem.
I am using id in an sql query, but not shown in my example (sorry :) )
But i wanted to show what i am after, and that is that the
id string cant be called after including index.php ...

In most languages, you must declare a function _before_ calling it. In
your case, your program looks like this after the include:
