This is half user's fault....
Can we do something to this issue?

To reporter: Could you update PHP version when you test and confirm problem exists in newer
versions? Read "Reference Explained" section carefully for the reason why this is problem
in your script.

the following script will print out
unset
set
the first time it is run although it should actually print 'set' twice; somehow, the
variable needs to be globalized again after the session has been registered.

normal php4 setup with everything compiled-in.
php -v >> 4.0.6devel
---------------------
function test()
{
  global $glb_var;

  session_save_path("e:\\temp");
  session_start();
  session_register('glb_var');

  test2();

  print "glb_var='$glb_var'<br>";

  global $glb_var;
  print "glb_var='$glb_var'";
}

function test2()
{
  global $glb_var;

  $glb_var = 'set';
}

$glb_var = 'unset';
test();
