[PHP-DEV] destructor access to constants

[Ulf Wendel]

Hi,

I'm wondering if it's a bug to give automatically called destructors 
access to constants (PHP Version 5.0.0b1). I'd expect to be neither able 
to access global variables nor constants after script termination (die()).

Ulf

$dtor = 'global $dtor variable is visible';
define('DTOR', 'DTOR constant is visible');
class dtor {

  function __destruct() {
global $dtor;
printf('$dtor = %sbr DTOR = %sbr', $dtor, DTOR);
  }
}
$d1 = new dtor();
unset($d1);
$d2 = new dtor();
die();
generated output:

$dtor = global $dtor variable is visible
DTOR = DTOR constant is visible
$dtor = 
DTOR = DTOR constant is visible

Global variables are a bit complicated but constants are either bound to the
class so they are obviously available in instance destruction or as in your
case they were registered in the global space and hence destructed after all
script action is finished which includes automatic destructor calls from GC.
