I\'m looking for a way to set the scope of require_once() to the global scope, when require_once() is used inside a function. Something like the follow

You will need to declare global in your foo.php:

<?php
 global $foo;
 $foo = 42;
?>

Otherwise it's probably not possible.

You could try to play around with extract(), get_defined_vars(), global and $GLOBALS in various combinations maybe... like iterating through all defined variables and calling global on them before requiring a file...

$vars = get_defined_vars();
foreach($vars as $varname => $value)
{
  global $$varname; //$$ is no mistake here
}
require...

But i'm not quite sure if you get to where you want to go...
