Is there a way to set the scope of require_once() explicitly to global?

Question

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

This is definitely not a "nice" work around but it would work:

function includeFooFile() {
  require_once("foo.php");
  foreach (get_defined_vars() as $key => $value) {
    // Ignore superglobals
    if (!in_array($key, array('GLOBALS','_SERVER','_GET','_POST','_FILES','_COOKIE','_SESSION','_REQUEST','_ENV'))) {
      $GLOBALS[$key] = $value;
    }
  }
}

However, your included file cannot define any functions or classes (and possibly some other things as well that I cannot currently think of) because it will result in a parse error, since you cannot nest classes or functions.

EDIT apparently you can include functions in your file. I had always thought you couldn't but after testing it seems that you can.
