It may be just "feature", but it is not documented to behave so:

If I include file within a function and that file declares global
variables, they are not really global:

file t1.php:
<?
  $T=1;
function Test()
{
  global $T;
  echo "T=$T\n";
}

  Test()
?>

file t2.php:
<?
function Test2()
{
  include('t1.php');
}

  Test2();
?>


'php t1.php' gives
T=1

'php t2.php' gives
T=
it is (unset).

If I define T global in Test2(), it works - but it requires
Test2 to know which global variables (configuration
etc...) Test() uses...
