Description:
------------
I needed to get a variable's or array's value when i had it's name stored in another variable. To get it, i used $$var_name; it all functioned as expected until it came across with $GLOBALS


Reproduce code:
---------------
//doesn't work, gets nothing:
$var = "GLOBALS";
$var = $$var;
print_r($var);

//does work: prints $GLOBALS
gettype($GLOBALS);
$var = "GLOBALS";
$var = $$var;
print_r($var);


Expected result:
----------------
i expected output exactly like print_r($GLOBALS)'s

Actual result:
--------------
but got nothing.
I managed to get wanted result when i added
  gettype($GLOBALS);
before the code;
