Description:
------------
If I have code that does a simple print_r() on get_defined_vars() it should echo out all the variables defined including _SERVER, however it acts as if _SERVER does not even exist. If you put "$_SERVER;" anywhere in the script it will act correct.

I have also found this problem exists very similer to _ENV also.

Reproduce code:
---------------
<?php
print_r(get_defined_vars());
//$_SERVER; // uncomment this to see another result
?>

Expected result:
----------------
it should also show the _SERVER and _ENV vars, but it doesnt

Actual result:
--------------
does not display the _SERVER or _ENV vars.
