Return from include file

Question

in PHP, how would one return from an included script back to the script where it had been included from?

IE:

1 - main script 2 - application 3 - included

Answer 1

includeme.php:

$x = 5;
return $x;

main.php:

$myX = require 'includeme.php'; 

also gives the same result

This is one of those little-known features of PHP, but it can be kind of nice for setting up really simple config files.
